Guitar is hard. It hurts your hands at first and you need to give it your full attention while learning to play. Those are challenges that few people want to deal with when it is far easier to make noise on your iPhone with preloaded samples and loops in Garageband. Hopefully, with fewer distractions (courtesy of Covid) there will be a new crop of great guitarists in a few years. However, I know for certain that there will be lots of lightly used guitars for sale in 2021 and they will be selling for pennies on the dollar.
Guitar is one of the easiest instruments to play simply, but takes a lot of lessons, practice and effort to play well. And it's very true that taking up the guitar on a whim is cheap and easy, but many people give up or lose interest quickly.
Beginners should start on nylon string guitars or light gauge steel strings. Your fretting fingers will soon toughen up if you practice daily.
That said, Stevie Ray Vaughan, one of the greatest blues guitarists of any color of all time, used to use super heavy gauge strings on his Strats, and because he would tear his fingers up with his wide bends, he would have to superglue his fingertips back together after his shows (or at least that's the rumour).
