You're pretty much correct, yeah. If you want to know what the actual benefit to playing a more expensive and/or name-brand instrument is, it's because it's largely a signal to others about your self. Playing a recognizable brand or a obscure-but-expensive brand can show to others that you're serious & knowledgeable about the hobby, instead of just playing a $150 strat clone you bought off Amazon. If you want to make money off of it, it's also a sign to your potential customers that you know what you're doing. Above like $500, they all play pretty much the same, but they make different statements about your self. It's up to you how much value that has to you personally, but please don't make the mistake of being surprised that others put a lot of value on how others perceive them. That little fact accounts for an absolutely enormous chunk of economy activity, it'd be silly to write it off as unimportant.

Yamaha makes fantastic stuff, they're a great choice.
