This seems like a blatant appeal to authority.
If it's not bad, provide reasons it's not bad. Throwing out Elon Musk's name does not provide any actual argument for your position.
he is a business man who only cares about money, and he uses effective marketing to make people like you buy in
Personally, I have purposefully chosen to live in a tiny apartment, in one of the few parts of the US where I'm not required to own a car at all. My iPhone 6S is six years old and I have no plans to replace it, and just yesterday I wrote an email to my building imploring them to turn down our heat, because opening windows in the middle of winter to stay cool is a terrible waste of energy.
I'm not perfect. I'm not a vegetarian, I don't buy carbon offsets, and I make use of Amazon's inefficient two-day shipping. And I'm not asking anyone else to go sell their cars. But would giving up Bitcoin really decrease your quality of life so much?
That is literally never going to happen through the nature of technological and human advancement. The solution is where you source your energy from, not reverting to the stone age or jogging in place as a society.
Being forced to save in a currency the central banks treat as toilette paper would indeed decrease my life quality specifically through the purchasing power decrease of my lifetime labor.
