People will consider several times the desire to send when transaction costs are expensive unless it is for reasons of urgent need.
This is not just a valid point for anyone not to spend their coin unless the coin is so little and below $10 which would also be wickedness to be happy that people can't spend their money. I believe this Mempool congestion issue is a problem indeed, an issue that most Bitcoin enthusiasts are even complaining about, it's better that a road is easily accessible rather than congested, what's the point if it's not easily accessible?
Contrary to your view, have you also thought about many people that was supposed to use Bitcoin for transaction but changed their minds to use altcoins due to this high fee issue? I don't see how this is a win for Bitcoin, maybe the increase in the market capitalization is what deceives you, it is for a pure investmenet reason, not forcibly.
