For individual humans that’s like saying ”My net worth is $100k and that is more than most people earn in a year”. Yes that is true, it is larger. But it is meaningless comparison and misleading at best.
Correct, and those countries' economies also give us little to no signal about US dollar inflation. The proposition was that BTC prices somehow inform us about that.
comparing GDP to market cap is also a very irrelevant kind of comparison. Just because the use the same dimension (like dollar) doesn't mean they are directly comparable.
