A little late to the conversation but wanted to chime in with a slightly different approach.
The conversation has been mostly around the technical aspect, lens quality, range of focal lengths, etc. I think that’s been covered well - and of course it’s ultimately going to boil down to what you end up feeling most comfortable with that suits your style and types of scenes you like to photograph.
From the above quote though, there’s very important aspect you left out; it’s not just a discussion about gear vs. post-capture processing/editing/cropping, etc. There is also the very important part of composing, framing and your vision in the field while photographing. You can have sub-par gear and capture phenomenal images with impact and meaning. If someone is pixel peeping on a 30x40" print, then yeah, glass quality and technique matters.
But in the end, quality images are more than just gear and processing pixels. It’s about vision and recognizing great potential at the time of capture. Having said that, having a zoom really helps in that vision and composition, allowing one to adjust literally on the fly, but it’s not paramount. On the other hand, primes often force one to “see” at certain focal lengths. I found this to be true when I spent many years using primes in the 4x5 large format arena.
Regardless of fixed primes, zooms or kit lenses or expensive glass - you must also include and learn to see and recognize comps and situations that have the potential for quality images.
