Hypothetically if some whale wanted to 'buy' Doge say to shut it down or something, they would probably have to spend a lot more than the market cap and as you yourself point out they still wouldn't have bought all the Doge that existed. OP was comparing amounts i.e $8bn seems like peanuts when 'joke' coins are hypothetically worth more than $44bn, and not really comparing market caps (which doesn't really make sense, again as you yourself pointed out).
