But actually, technically, you can’t earn bitcoin. That would mean you own bitcoin.

Yip, that's why I like Monero. Everyone has a CPU so they could earn, even a little bit.

For Bitcoin you need a big rig to compete, and once the subsidy is gone you'd better hope for enough fees to cover your costs.

For the majority, they can't afford one bitaxe or ASIC miner, let alone 100x in a container.

Most places in the world don't have electricity to mine either, so it's exclusionary in my view.
