I mean, you can do that, but you have to consider a lot more things:

- Are these assets authored in a way that's friendly to my game engine of choice? IE, will the materials import correctly, will animations be correct, are things scaled properly, is the Z axis up or is it forward, etc. Having dealt with importing files between various engines and 3d modelers, seamless importing and exporting is no small thing.

- What's the license, and are the licenses standardized? Do I have to pay royalties or record attribution?

- What's the selection on these sites? Do I have to enter my payment info into like 20 different sites?

- This also only covers art/sounds. Unity has a huge selection of code assets that are incredibly useful.

None of those are insurmountable of course, but having one place that solves all those problems is great.
