Even if its possible, it would take days or weeks to get that much BTC. What if you want 2,000$ of BTC right now? Would you want to wait months before you get it?

I was a click away from buying a rig rig a few years ago. I wanted to build the rig because that seemed like the fun part. I even had excess electricity from solar panels, but chickened out.

Bisq sounds interesting, but I have my doubts about them, since there is no escrow system and I don't think there is enough liquidity either. I'll check it out anyway.
You just described how to buy bitcoin privately with electricity. Why is it unrealistic?
