How the price is determined is irrelevant in my mind.

If you know the price, you can choose to accept it or not.

I never took a taxi with posted trip cost. Best was price per mile/time and the cabbies wouldn't tell you how for or long it would take

Note that the economic term for this is price discrimination, and it isn't necessarily a bad thing: https://www.investopedia.com/terms/p/price_discrimination.as...

Seller price discrimination is a different phenomenon from what I am discussing.

I am hinting at how ex-ante price disclosure or negotiation reduces transactions costs of triangulation and trust.
