If you use prime lenses you are an archetype of consumer made flesh. There is zero (0) reason to own even one (1) prime lens on a digital camera. On film cameras they are allowed, as film is inherently anti-consumer so you get a pass.

> primes are sharper

Irrelevant argument, if you know how to take sharp photos you can take them with any modern lens.

> primes are faster

This could be true, if you would ever actually need anything faster than 1.8, which you do not. Nose in focus, ear out of focus (bokeih?!). Only relevant if you use a meme system, that is anything besides 1'' BSI sensor.

> primes limit you, therefore you need to be more creative.

If you need any external limitations that are not self imposed, you are an brainlet. Do you also need a porn blocker to be able to resist porn, do you need strict laws to keep you a moral person?

> primes are cheaper

A single zoom lens is worth as many primes as it is its focal length range. My G7X is worth 76 primes, as its zoom range is form 24-100mm. If you choose to believe in Cantor's diagonal proof (skitzo), each zoom lens is worth an uncountable infinities more than a prime lens.
