Since we're given ordering and enumerations for the Down clues, it might make sense to start entering those into the grid. From there, we can make observations about where certain Across entries have to appear, and then where there need to be bars added in. It turns out that there is exactly one vertical bar missing in each row. Here's what the grid looks like, filled in with answers and bars:


From here, we can turn to the flavor text. It says that we want to be "right beside" the bars--that indicates that we should just take the letters that come directly to the right of the bars that were stolen and that we put back in. Extracting like that indeed gives us the final answer of STEEL EMPIRE.


Author's Notes

I was happy to provide a cheeky little callback to Monopoly Hunt with this puzzle.

Here are the clue explanations:

Across

  1. I see TAs bizarrely losing energy to nap: anagram "I see TAs" without one of the e's ("losing energy") to get SIESTA, which is a nap.
    Leading quintet traded top cellist for entrance to opera house: "Leading quintet" clues ABCDE, then trade the C for O ("entrance to opera") and get ABODE, which is a house.
  2. Author excited at win: anagram "at win" to get TWAIN, an author.
    Military base knocks loudly: take a homophone of "knocks" to get KNOX, a military base.
  3. He says hello regularly for support at the studio: take the even letters ("regularly") of "He says hello" to get EASEL, which can be a support at the studio.
    Shoe for the answer below this: this is a double definition. In the grid, the answer below this one is REPTILE, and so both halves of this clue can be satisfied by the answer CROC.
  4. Night before first lady: this is a double definition. A night before and the first lady (biblically) are both EVE.
    Triple E obliterated cold-blooded animal: anagram "Triple E" to get REPTILE, a cold-blooded animal.
  5. A little pellet to back superior monk: A + BB (little pellet) + OT ("to back," i.e. reverse "to") gives ABBOT, which is a high-ranking or "superior" monk.
    Pam allegedly held back pack animal: LLAMA, a pack animal, is hidden backwards ("held back") within "Pam allegedly."
  6. Emperor botched rats: anagram "rats" to get TSAR, an emperor.
    Results: Graf almost took first championship on ecstasy from the east: Graf is STEFFI, "almost" means get rid of the last letter, "took first championship" means insert a C, "on ecstasy" means add an E to the end, "from the east" means reverse the whole thing. From there we get EFFECTS, which are results.
  7. Small echo matching opening word?: "Small" = S, "echo" = E, "matching" = SAME, and SESAME is an "opening word" (as in "open sesame").
    Um, no, silly, time to get up: anagram "Um, no" then add a T ("time") to get MOUNT, a word meaning to get up.
  8. Knock back green object?: "Knock back" means reverse RAP, a word meaning "knock," to get PAR, which is a "green object" in the sense that on the green in golf, one's object is to shoot par.
    North America 5: U-Turning Auto: "North America" = NA, 5 = V, "U-Turning" means to reverse everything, and VAN is an auto.
    Young foxes get no stitches: "Young foxes" are KITS, "get no" means to insert an N, and KNITS is a synonym of stitches.
  9. Head of green-eyed monsters is valuable: take the first letters ("head") of "green-eyed monsters" to get GEM, a valuable.
    Little bit of Tours yours turned up: "Tours yours" clues "À TOI," which means "yours" in French (Tours is a city in France), "turned up" means to reverse the string, and an IOTA is a little bit.
    Tête-à-tête derived from Greek letter: this is a reverse letter bank. "Tête-à-tête" is made up ("derived") entirely of E, T, and A, and ETA is a Greek letter.
  10. Brief suggestion concerning Charlie: "concerning" can be written as RE (as on a memo), "Charlie" = C, and a REC is a brief suggestion in the sense that it's a shortening of "recommendation."
    Put down Albany evenly: taking the even letters of "Albany" gets LAY, which means to put down.
    South Park victim's broken nylon stocking: "broken nylon" hides (is "stocking") KENNY, who is a frequent victim in South Park.
  11. At heart, Emerson makes hospital sites: the center of Emerson ("at heart") is ERS, which are hospital sites.
    Finally, someone from Tokyo taught me to overdo it: taking the last letters ("finally") of "someone from Tokyo taught me" gives EMOTE, which means to overdo it.

Woodstock band casually entered outside arena in African port (5): "Woodstock band casually" clues CCR (Creedence Clearwater Revival is casually referred to as CCR), "entered" means we put those letters in something else, "outside arena" means take the first and last letters of "arena," and putting those together gives ACCRA, which is an African port.

  9. MA city screwed up meals (5): anagram "meals" to get SALEM, which is a city in MA (Massachusetts).
    Small dome within Łańcut, Poland is not true (6): look "within" Łańcut, Poland to find CUTPOLA, then take out the T ("not true") to get CUPOLA, which is a small dome.
