No, I'm sorry but you are ignorant.

I agree that a 2 million $ guitar isn't better than a 2k$ guitar.

But a 2k$ guitar is certainly better than a 50$ guitar. Not only in how it sounds but in how easy it is to play it.

My 1st guitar was bad so I couldn't do barrè chords. I thought I was bad and pros could do it. Turned out pros just had better guitars.

Better guitars also have less noise, better cables are shielded.

Yes, more expensive is better (up to a point).

Yes. However, the instrument being better just means the sound it makes will be better, not that the music the musician makes with it will be better.

I just gave you an example of how it's easier to play, allowing more music to be played...

It's not just about the sound.
