They have no regard for the market cap
Market cap is one of the most broken and redundant measures that there is. To put it politely and use your own eloquent language, you're retarded for thinking it matters.
They're not concerned about actual usability
You're confusing here the few with the many. Plenty of people understand that bitcoin needs a utility for it to continue to grow or else your 3rd point will remain true forever. Inevitably when you get so many people bullish on a technology and its potential you will get some who are only around for profit and don't understand the underlying tech.
When you're considering fees, there have already been advancements to try and prevent what happened in late 2017 from happening again, and there will continue to be so. With anything when there's an influx of new demand its hard to deliver. Scalability is always an issue but it's being worked on. The very fact fees got so high shows BTC is a success because it was driven by people using the coin.
Bitcoin is something speculators use to bet against other speculators
Can't argue with that, that will always be the case and it is for every other currency. It's not a criticism of any merit, it is the same for FIAT currencies. But like those FIAT currencies, it is not bitcoin's only use.
