He makes some good arguments, but misses some key components.

For example, he doesn't address the fact that D.C. is run by the same government as the U.S. but under a different guise. E.g. the President is the CEO of the D.C. municipality per the Organic Act of 1871 and revisions on that act in 1878 and 1973(ish).

Also:

So what The District of Columbia Act of 1871 did was nothing more than create a government called the District of Columbia as a municipal corporation. Meaning the district can legislate, enforce, and contract with others.

Here he doesn't address another key component of municipal corporations, the ability to create and sell bonds, i.e. go into debt. Who owns those bonds? I don't know, but I'd bet money that the ultimate owners last name starts with an "R" for no small percentage of those bonds.

While bond ownership doesn't give rights to tell a municipal corp. what it can and can't do generally, it does provide that right if the corporation is in default. Realistically, it also gives real leverage if you own enough bonds (see The Fed or the mafia).

In 1933 this default (bankruptcy) may very well have happened. Bond ownership also gives the right to the bond owner to demand taxation on the citizens who are bonded (that's what a municipal bond is, a bond on the citizens of the municipality i.e. an indentured servitude). This is no small deal. Again, see 1933 and also 1913 for when this might have played out on the larger U.S. even though it should have applied only to the citizens of D.C.

The combination of the same people in government being a government for both D.C. and the U.S. plus the rights associated with bonds gives plenty of opportunity for fuckery and may very well be the legal path taken to declare bankruptcy in 1933 (maybe, not 100% sure on that), confiscate all the gold in that same year from the entire U.S. citizenry and give it to the Fed (which did happen), and possibly instigate the taxation of citizens to pay the Fed through the IRS which is I believe a private organization (not 100% sure on that either, but there is good evidence to support it), having nothing to do with the government (IRS inc was also started in 1933).
