I think they're being sarcastic because reducing the tradeoff to "a small bit of your equity" in exchange for "100x MRR" is misleading, to the extent that it reads as sarcastic ignorance.

FWIW, I vouched your original comment because I think your comment represents an authentic view shared by other people on HN / in tech.

My question for you: how do you price the stress-potential of hiring, managing, and firing / being fired by (1) a board (2) employees (3) cofounders / other executives; each with their own set of competing incentives and accompanied principal-agent problems?

It's certainly not zero. For many people, it's more expensive than the hypothetical marginal increase in MRR.
