There's a fundamental material difference between Uber/Lyft/UPS and ISPs -- the initial costs to get into business for people/package transportation services are orders of magnitudes less than for ISPs.
The minimum cost of a transportation venture is extremely cheap -- a working vehicle and its operating costs (petrol, insurance, maintenance). Of course, it won't be as profitable as UPS and such a venture won't be able to out-compete UPS nationwide but there certainly are small local courier services that provides faster and cheaper service than UPS for limited use-cases.
There is no equivalent of a public national roads network for ISPs -- stringing up fibre is expensive as all hell and involves having to get permission from land owners, municipalities, and utilities. National-scale incumbents (who can easily afford to throw a few million dollars here or there to put in fibre of their own in a new region/market) currently are not subject to real competition from local ISPs (who don't have a comparable ability to throw cash around).
