no it will never will.Why? because not every people on earth have access to any hardware that are required to store bitcoin not even on year 2022. also the thing is if it will be used by people what if there is no electricity on a certain area. then no money at all. ?
But the fact is that electricity and network coverage is expanding at an incredible, ever growing rate right now. There is simply no mistake by saying that bitcoin will be used by everyone in 2022.
Your argument is as weak as saying that because there are no printing presses in a certain area, that area will have no access to money. First of all they will still be able to hoard their money, and second there will be a time when there is a printing press.
