The analysis above is kind of nonsensical because not everyone wants to own
Bitcoin, some have more than 1, more than 10, more than 50 already.
It is also necessary to take into account the fact that bitcoin has a limited quantity, and the human population is conditionally infinite (due to the ability to reproduce and multiply in progression), which will reduce the possible amount of bitcoin per person. That is, the availability of bitcoin will decrease (due to the increase in the number of holders), and the number of people wishing to purchase (even taking into account the fact that not everyone wants to receive this asset) will increase.
Despite some inaccuracies in the OP's calculations, in general, the trend he voices (there will not be enough bitcoin for everyone) seems relevant.
I dont care how much everyone in the world would get if Bitcoin was hypothetically redistributed.
Uniform redistribution is impossible, especially since bitcoin is already distributed very unevenly. But such is human nature, because any resources (the majority) sooner or later become concentrated in a small circle of people. Which suggests that bitcoiners (single and with a small number of btc) will have to compete with big holders (corporations and countries) in the future, and will have
to play against them.
