Think about purchasing a physical mini. When you buy a goblin sculpt off a shelf at your local game store, you don't usually get any stats with it, and you aren't handed a set of goblin minis when you buy your Monster Manual.I guess the fact that I have never used a VTT is showing! My concern would be if I purchased the "mini" don't I also get the stats for it? How does it function without the stats? And why would I have the stats without the mini?
The process of using an art asset on a virtual tabletop is pretty analogous. You have a picture of a goblin (or a 3d model of one) that you bought in an asset store, and you have the stats for a goblin you bought with your digital Monster Manual purchase, and then you're just telling the system "when I click on this goblin mini, bring up the goblin stats." You could also put an orc mini in and tell it to call the goblin stats as well.
