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.
Government can do the unimaginalble things. That includes seizing properties and alike with a reason of something like they are doing it for the "people". So yeah, the event like confiscating Bitcoin isn't far to happen.
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.
By having Bitcoin at 8 decimal places to the right of zero, this give the current bitcoin a 2.8 quadrillion supply of bitcoin not the 21 million supply that a moron such as yourself believes. In addition, moving even further to the right inflates bitcoin supply as moving to the 12 decimal place to right of zero (like LN is doing) increases the bitcoin supply to 28000 quadrillion supply.
I believe adding maximum supply for Bitcoin is very possible since it is only a program that anyone with authority can modify. As long as developers reach a consensus of adding supply to it, then it will happen. But adding 0 to the right after a decimal point won't change the fact that BTC has a 21m limit in numerical terms of being a whole number.
So the US could print all day long while the adding decimals to the right of zero in bitcoin, and you still would be clueless.
The first part is true but the latter part is kinda debatable since it is yet to happen.
