Remember early in 2021... and likely the same way ever since? The White House was (is) basically a ghost town. On Pennsylvania Avenue which connects the White House to the capitol, all those buildings including the FBI, Department of Treasury, the Labor Department and others were basically abandon. Washington DC was a heavily guarded, fenced encampment.
During 2021 & 2022, there were attempts to make it look like Joke Biden was residing, or at least leading from the White House. I haven't even seen feeble attempts recently to make it appear that he's in the White House.
Question: Are the main government buildings in Washington DC still closed? Is it still a fenced and heavily guarded compound? Is the White House empty still?
Next question: When U.S. Corporation becomes bankrupt and cast off from the Republic of the United States, does everything within that fenced area become foreign territory, including the House and Senate?
The Neighborhoods/Commercial Areas part of D.C would likely revert to the control of the State they were originally portioned off of. The Government Buildings would remain under government control.
Which fun fact. Was tried once before. Only Virginia took back their portion. Maryland refused as the introduction of such a large urban center would swing the balance of power away from Baltimore.
But there’d be no reason to declare it foreign territory. As it technically would just be a creditor collecting assets of a defunct company. And frankly explaining the overcomplicated legalese that even proponents of the Corporation Theory can have difficulty explaining. Wouldn’t actually do anything or be useful. Except make people on one end of countless internet arguments feel validated.
The most we will probably outwardly notice. Is maybe some name changes on Federal Buildings. And edits on some Maps. But no significant changes.
