Your enjoyment on bitcoin is likely contingent on mass participation. If you owned all of it, your entertainment-per-BTC would probably be a lot lower.

Pinball machines are fun with or without this. Warren Buffet is saying he wouldn't want all bitcoin (in this hypothetical scenario where it is 100% concentrated under a single owner) because there is no reason for him to believe he could sell it to anyone.

Creating demand for essentially nothing is way harder than creating demand for something that has immediately demonstrable economic value. This is why crypto is so full of scams and pyramid schemes and shady marketing.

Would it still be entertaining if you owned all the bitcoin and nobody else used it?

Pinball can be entertaining without a market for pinball machines, I don't see how bitcoins would be entertaining if there were no market for them.

Great! So long as people like you exist, bitcoin has value .In fact, in my opinion, the entertainment aspect has been the main driver of bitcoin and other crypto value over the past year. In fact, almost any pump and dump is really fun for all players. It only settles in after you end up bag holding. It's like gambling.. People consistently love to lose money.

So if you view bitcoin as a consumable you are consuming to provide entertainment to you, that's great. I'd personally take a lower cost source of entertainment, but to each his own.

Personally what I have almost exclusively used based on bitcoin is its altered codebase litecoin.

I have used it exclusively for lowering transaction costs, lowering my cost to buy bullion such as silver. Most vendors in the US do not have any lower cost of buying bullion online in a way that clears under an hour, particularly during times when they wave crypto fees. ACH and wire (sometimes) can be free but never clear (for me) in under an hour (and on occasion even get held up for days), and I find the counterparty risk of waiting 1-3 days unacceptable.
