I agree, and the mandatory question right at the top of Form 1040 is just the beginning. No doubt the government will want full self-reporting of every wallet address you control in the future. But the fact remains - if you fail to comply with fiat regulations, then the government can take your fiat out your bank accounts with ease. If you fail to comply with bitcoin regulations, the government can't take anything unless you hand it over to them.

Because some people wrongly assume that any coins which has not moved in 5 or 10 years is "lost" and therefore removed from the supply, and therefore any coins which have been dormant for this long and then "wake up" again are effectively inflating the current supply. This is obviously nonsense, as has been proved many many times in the past. The only coins which can be removed from the supply are those which are provably lost or burnt, and those coins number a few thousand at most.
