It's not a simple semantic distinction. The mechanism matters because the monetization is built around it, and the monetization (as we've built it) only works because there's a human on the other end.

Can we build other monetization? Maybe. There's certainly proposals. It's real hard when there's too many layers between the user and the output though. I suspect the solutions will be worse than what we have now. For now the answer is "just paywall", but given your invocation of "corpo" here I suspect that's not an outcome you'd be too keen on ;)
