You sound so convincing but what is your basis? Why will Bitcoin "never exist in a value vacume"? Why will "other options" always come out on top for other people? Sounds like you're a Monero guy just dying to tell us about it.

Because no such exchange commodity in the history of humanity has ever existed in a vacuum. There will always be multiple currencies, and things resembling currencies.
Existing Bitcoin holders are the worst offenders here. On the whole they don't spend their Bitcoin, except for a little "show off" spend here and there. Basically Bitcoiners killed Bitcoin's future as a medium of exchange by leaning too far into hodl and stack thing, and they only have themselves to blame for Bitcoin now being unable to establish itself as a medium of exchange and forever a Store of Value, treasury, etc.
Up to about 5 years ago there was a chance to steer Bitcoin in the MoE direction, that chance has gone and will never come again.
Nah.
