There is truth that at times procrastination is tied to perfectionism, but I'd wager that the cause of procrastination 9/10 times is that we choose to do something that is more enjoyable to us over something that is less.
I don't know if I'm in the minority or the majority, but I can say my experience definitely doesn't match the view you're invoking.
When I procrastinate due to my perfectionism, I pretty much never do something enjoyable instead. Rather, I frequently lament that I don't have enough time for fun activities.
When I'm procrastinating in a WFH setup I could easily play video games, watch a show/movie, read a book instead, but don't. It's almost as like a punishment, rather than a reward.
