I've seen you make some stupid posts before, but this one truly is special. You really must be running out of arguments if this is the straw you're clutching at. The infinitesimally small chance of this happening aside, there will never be enough bitcoins to back all the money they keep printing.
Considering history is something you always been clueless too.
The fact that the US Government seized gold in the 1930s is beyond your limited understanding.
Physical gold is far easier to seize than something like a seed phrase when employing encryption to its full potential. I could disguise my private keys within images or other media and send them to any corner of the planet I choose. Anyone who has had their BTC confiscated simply wasn't taking all the precautions they could have taken.
Also your failure to understand the number of bitcoin is not limited at all.
Bitcoin is inflated to the right side of the decimal so fools like you think their is a limited supply.
It is already well established that division does not create more of something. If you believe you can prove otherwise, please do us all a favour and cut yourself in half.
