For example: most small, plastic toys should not exist, regardless of how many people might want them. They’re essentially mass-manufactured pollution that harms the global environment. Sure, you can find positive effects of them, but I argue those effects are not worth the downsides.

There are many other things that would be a net positive of they didn’t exist.

Just because something can exist, just because some people might want it to exist, doesn’t mean we’re better off. Honestly I think the Amish and their measured approach to technology is correct (though my rubric would be different than theirs).
