> I sometimes know what product I wanna buy and I enjoy that I can more or less trust that among reputable stores

That's fair. You can have all of that without trademark or copyright though.

> a product carrying the name and logo of the product I wanna buy is the product I wanna buy.

Lots of products can carry the name and logo of the product you want to buy without trademark :)

Maybe there is something besides the logo that you're more interested in?
