20k for such a setup for a hobbyist? You can leave the somewhat away and go into sub 1% region globally. A kw of power is still 2k/year at least for me, not that I expect it will run continuously but still not negligible if you can do with 100-200 a year on cheap subscriptions.

There are plenty of normal people with hobbies that cost much more. Off the top of my head, recreational vehicles like racecars and motorcycles, but im sure there are others.

You might be correct when you say the global 1%, but that's still 83 million people.
