The biggest problems I see with mining is that it is a waste of computing power, energy, and labor. We could be using this computing power for AI, exploring space, or solving world problems. Instead we are using up a ton of resources like electricity and producing nothing tangible in return. On the other hand our current banking system does use up a lot of resources to produce and maintain currency. I just wish there was a way to be more planet friendly when producing a digital currency.
No fucks can give about the computing power itself, moreso the amount of power used, like you said. under ideal circumstances, miners can be built from pre existing parts on certain algos. so for the environmentally conscious miner, btc isnt even really an option at the moment, but alt algos still can be profitable to mine. but the power, despite the device, is the real problem, its a waste of a resource that is really needed for something more practical.
the labor is a benefit, imo. there is nothing wrong with value creation, just so at the sake of safety/longevity.
