Transaction issues are temporary, it will go away in some time. But considering how US is taking actions against crypto companies since last couple of months, I don't honestly see a green light at the end of the tunnel.
I agree the US is trying its best to suppress all the originations, exchanges, and other bodies that are somehow connected with the trade of Bitcoin or are providing Bitcoin to US citizens. But, states like Florida and their citizens are favoring Bitcoin and in that matter the Federal government will definitely interfere with them.
I understand that US has a federal structure, but do the states have power to ignore a government controlled currency system? I am not sure but it seems states do not have an option here. It's good to see that call for adopting Bitcoin but avoiding CBDC, doesn't looks like an option for the state government and also for the citizens.
No, the states can't ignore the US dollar because they don't have that power. The constitution of US grants the complete power to congress and only congress can make a currency and regulate its value. As you know that US dollar is currently the official currency in all states and that's the reason that states can 't restrict its usage.
The states have limited powers in this regard and they can only increase the taxes to some extent on dollar but they have no power to create or declare their own currency. And they also lack the power to refuse the US dollar as payment for debts or taxes etc.
