Without the USA, the world would be at the mercy of the two remaining nuclear super powers, e.g. the dictatorships of Russia and China. Be careful what you wish for. And Bitcoin isn't going to help you if you live in a dictatorship.
After the Cold War the world has been at the mercy of a single dictatorship that murdered over 30 million people across the world because it is the only "pole". A multipolar world is a much better and
balanced world in comparison.
but he can't do anything to stop the monetary/debt problems
It is actually very easy to solve majority of those problems. The solution is stop overseas adventures and go back home! That is where the taxpayers money is being wasted.
For example one of the biggest cases of hemorrhaging money is what G.W. Bush started more than two decades ago and it only gets worse with every passing day. That alone is more than $12 trillion and counting.
That is only going to increase
exponentially because the day war criminal Bush was feeling like a "big guy" declaring war on 7 countries, little did he know it would be turned into a war of attrition to wear down US military and US economy both.
To put that in numbers, eg. these days US Navy alone is wasting billions of dollars just to survive and stay afloat in the Red Sea and its neighborhood
without accomplishing any of its goals! That's while the attacks they're deflecting aren't even serious
yet.
All that can stop and trillions of dollars could stop being wasted and instead be spent domestically to fix the local economy and the aging infrastructure... only if they give up such adventures and go back home becoming a normal regime...
They're not gonna do that though, neither Trump nor Biden... This is why USA needs a regime change not a president change. A new regime which is not controlled by a minority of ultra wealthy people like arms dealers who got rich of that $12 trillion of taxpayers money I mentioned above.
Other than that I agree with your points about Trump.
