I guess a large reason why is because, especially with miniatures, it doesn't require any equipment to actually make the thing. Bear in mind 3d printers (or at least the ones the average person can buy) are still quite new, they were unheard of when I was into warhammer as a kid. If you wanted a miniature, you had to buy it from the people that made it. Even now, its easier, if more expensive long term, to go to a shop and just buy the things than to print one out. As for magic cards, I remember as a kid printing off yu-gi-oh cards, but they never ended up being very good, even with access to a laminater (we had to go to the library to do that). It was a short lived idea sadly
