Even 7 or 8 years after Bitcoin was created, most people could afford to buy half or even one whole BTC, because $200 or $400 is not much money for most people in the developed world.
The funny thing is that people were complaining about "early mover advantage" back then too and claimed that $200 is too much since they've lost the opportunity to buy bitcoin "cheap". Complaining about the same thing now at $20k isn't any different and they'll do it again in the future when price is $200k and $2 million too, instead of buying bitcoin now!
