The time will also come where we will not talk about buying bitcoin, but instead buying satoshis.
Currently, with the price of Bitcoin, only a few people are able to afford to buy a full Bitcoin; many can just acquire units of Bitcoin, and that's okay by them. Only the wealthy are looking forward to buying one full Bitcoin. Anything anyone can afford can give you profit. Bitcoin has really grown up to almost that level that you are talking about now.
Exactly, and many small retail investors are already buying SATOSHI, accumulating like that until they get enough fraction they can call a significant amount of Bitcoin. So, what @MrBitcoin1997 has said is something that is already happening and not something that is yet to happen in the future.
