You don't need to buy bitcoin there are a million satoshi and users will start buying and holding satoshi not bitcoin.
Bitcoin will be for whales or institutional investors. in 2013 people was tipping more than 5 bitcoin.
Some Bitcoins that have been reported as lost will be found. i know many of friends recover wallets that they have forgotten or not remember the private key.
Well if you can remember a private key you are touch by the gods! jajjaja
That's funny though.

I have been seeing posts here asking for help how to recover their unforgotten wallets.
If you manage to recover your wallet and found out that you have lots of bitcoins, then you are one lucky person, winning like in a lottery.
But yes, we don't need to buy the whole bitcoin to be a crypto user, these days owning satoshis is more common to ordinary people.
Even long time crypto users here don't have 1 bitcoin in their account. Maybe in previous years, but I believe most of us don't have one.
