It's not a non-existing problem.
For example, I live in Russia, and the only way for me to support creators I like is sending them crypto. All traditional channels were blocked by sanctions; crypto can't be. Besides, it's irreplaceable for political activists and many other people who can be cut off funding on a whim.
I'm not a crypto maximalist saying Bitcoin should replace national currencies, but I understand the value and power of crypto. It does have its place in the world.
As for mining, primary reason for GPU market shitstorm (which affected me personally as a non-miner and gamer) was mining Ethereum, which has now changed its validation model and does not need any GPUs anymore.
Cryptocurrency scams and NFT bubbles are real, and I urge people to he aware of them. But it doesn't mean crypto should die.
