Your faith in "NFTs and crypto" should be shaken, its scam garbage. Welcome to the party.
Your belief that inflation is good because it creates spending is fundamentally flawed, and its one of the core reasons everything is so broken right now (rejection of our Christian roots in the West being the other). This belief is fundamental to Keynesian economics as it is used today (Quite different then how Keynes intended for what its worth). The reason you, correctly, believe that it would be stupid to spend BTC is due to
Gresham's Law which basically states why would you spend valuable money (BTC) when you can spend crappy money (USD). Hard money completely transforms the psychology of a population, you're not going to spend hard money on crappy plastic Chinese garbage, your only going to spend it on high quality goods. That is not a bad thing no matter how much your economics professor told you it was. Humanity has been on a hard money standard for it -entire- history up until quite recently (at least 1971 with the closing of the gold window but potentially as far back as 1913 with the formation of the Federal Reserve depending on how you want to define it).
If we were to move to a world with Bitcoin as the backing for international currency, what you would see is that the price of -everything- would decrease over time. This is actually how it would work naturally. As technology advances it makes things cheaper to create or do. As such the COST of doing those things should decrease. You can't do that with an inflationary currency though so everything gets more expensive forever even as we become for "advanced". This is compounded by the ability for a small group of people to print the very currency that the rest of the population has to work for.
I'll leave it there, people will only horde their "Scroge McDuck" money until the bad money is driven out and the good money replaces it. This is part of a transition from one system to another psychologically, not a attribute of the good money in question.
Also next time someone is willing to accept Bitcoin for service, you should totally do it (assuming they're any good). Just buy the Bitcoin on something like Strike or Cashapp and send it to them immediately, its no different than spending USD from your perspective, but they get to live on a Bitcoin standard which is the whole goal.
