ELI5:Why do people fret guitars with their non-dominant hands when fretting is harder than picking?
gpt
The important thing about the dominant hand, is that it allows you to do very small movements very exact. And that's what you do with the picking hand. Pressing the frets isn't complicated it's like pressing buttons, just put your fingers at about the right place and press down. So i guess it's just simpler to begin with, put your non dominant hand down and just let it rest there while you try to pick some cool notes with your dominant hand. 


But there are some left handed guitar players that play with "normal" guitars and do it just as good as everyone else. At the end it comes down to what your used to and your preference. And as soon as you go to fret less guitars/instruments you need to be very accurate with both hands. And the only thing that will make you good is intensive practice of both of your hands. If you have a non-dominant hand while playing an instrument you just haven't practiced enough.
