It would not be legal to DO so anymore
Bailouts would be one thing, but as of now, a tax to support the USPS operating costs would not be legal.
The only tax permitted under the reorg act in the 70s was stamps ... And since the early 80s, stamps have been a "postal product"
Fitz, I like you, but I nominate this as possibly the dumbest thing anyone has ever said on APS.
"It's illegal for the government to tax."
If it's not Constitutionally prohibited, and merely a component of USC, Congress and POTUS can do whatever the hell they want. They make law every day. They BREAK law every day.
If they need to change a law while writing a law, they do it with no compunction whatsoever. They have tomes of multi-thousand page revisions of USC just waiting to be put on the floor of the House or Senate as bills. Congressional staffers must have produced millions of pages of bill proposals per year prior to the digitization of everything.
The 1970 postal reorganization act is USC.
