This is true, except that the "selling commodity at a loss" and "legal exemptions" examples both presuppose that you already have product-market fit for the commodity you're selling or the thing you're getting an exemption for. If people fundamentally don't want what you're selling, aggressive pricing and legal lobbying will only lead to you killing yourself that much faster.

This is something we tend to take for granted with already-successful companies, but there was a time when everyone — even Uber and DoorDash — were struggling in obscurity to build something people would use.
