> I have never heard of a business that reaches $x of profit and then switches to pricing everything so that they get $0 of profit.

Isn't this the business model of tons of huge companies? Amazon famously ran at very deliberately low profits for years. Uber and Lyft have margins so low they're losing tons of money in an attempt to get market share.

No. Operating at low profit margins is not the same as reaching $x of profit and then selling everything at cost.

These do not seem relevant, as most businesses, by and large, year after year, are not giving away products or services to try and gain marketshare.

Eschewing profits now to fuel growth with the intention of making large profits later is the exact opposite of that.
