I'm still amazed how Bitcoin can damage the environment by just existing yet AI, air conditioning, aluminum smelting, and cat videos have subtle effects that are hard to determine.
And, of course, let's not discuss:
- tourism + air travel
- increasingly large cars far bigger than required from a utilitarian perspective
- luxury good production
- theme parks/fireworks displays
- cruise ships
Etc.
Bitcoin/crypto opposition is 95% pushed by embedded financial interests that will use any lever to protect their control over money and the power it gives them.
