Yous lose much credibility citing Zimbabwe, Wiemar Germany and Venezuela as a warning to the U.S. You lose more with all the claims of the Fed "printing money".
Two of hose three countries were tiny players in the global economy, all owed large debts in non-national currencies to foreign nations and creditors. None could use their own currencies to service their debts and all lacked the economic power to obtain "hard currency" or commodities to do the job.
The U.S. is still the most powerful economic player on the globe, its currency is by the global reserve currency by default; no other currency engenders the trust or is backed by a legitimate government/legal system and national productive capacity to do the job. It owes all of its debt in its own currency and a significant amount to itself.
The Treasury prints money, that printed currency is a bit player in the U.S. and global economy. The consumer, business and unemployment support being paid into the economy is replacing consumer dollars lost as unemployment soared and businesses closed. The current problem is to keep enough dollars in circulation to prevent further business collapse and unemployment. soaking that currency back out of the economy when/if production and consumption rebound is the next problem, one that won't matter if too much damage is done to business and employment.
