Depends on the product, a lot of things exist to be ad bate, and don’t really serve a wider purpose. Tshirts is an example that comes to mind where people just buy dozens of designs they never wear.

So I guess sans ads we would see a lot less arbitrary products (and places like Amazon would take a hit [yay])
I would be curious to know how e-commerce would change though as without ads people would likely gravitate to the big box stores
