So unless you can conjure 430 Billion USD out of your ass without any inflationary effect then America just lost a third of its defence budget and power.

And Europe's defense would be cut down to a third. America will do fine defending a much smaller area with a slightly smaller defense budget. Europe, I doubt it.

I think the possibility of America leaving NATO is the only thing that I can see as a good thing on the horizon. I cannot wait until Russia steamrolls you all the way to France and I never have to hear about ungrateful Europeans from behind the Great Firewall that Putin puts in place for you.

I'm sorry to be the one to break the news to you but every NATO agreement is with the USA as an intermediary. Applications are sent to the USA and approved by the USA.

Without the USA all previous NATO agreements will become void. Until a new organization forms without them, there will be no pact holding the countries responsible to defend each other, and it will likely be difficult to get countries that weren't at immediate risk before to join the new organization given it lacks the USA's firepower as a guarantor against the potential enemies they could make.

Decades of progress put into making the alliance will be gone, and it will become everyone's problem sooner or later. The USA will become a frontline when allies start to fall.
