I sometimes see how artists who I follow on Bandcamp write about their struggle with ordering the production of vinyls, shipping delays and troubles, etc.

I'd rather them spend this time on doing their art, or going on with their lives. If you want to give an artist a token of appreciation, send them money. I always increase the suggested price of an album or track on Bandcamp to some interesting-looking number.

To produce, ship, and store an otherwise unused complex artifact just as a token of appreciation which is not otherwise enjoyed by the parties looks wasteful for me.
