Hard disagree.

You may want a THING, but you don't know about a particular brand or style of said THING. Just by making you aware of them can be a win win.

Say you've been researching "THINGS" for a couple weeks and narrowed it down to 2 brands. An Ad pops for a brand you'd never heard of. Naturally you check it out, only to find out its better than either of the options you were previously considering.

I trust myself to find better products than what random ads will suggest. In my experience, that holds true. I hardly ever purchase anything from "new" brands except for niche products but ofc YMMV

There's so much noise online now, ads are necessity for me to eventually find something I like.

As an example, a couple of months ago I was searching for some new summer outfits. Went through Google, Reddit, various clothing blogs, catalogs, etc. but didn't find a lot that I liked. After a week more of targeted ads on Instagram, I was finally able to discover brands that fit my tastes.

Unless I'm buying something well-defined like a TV or Airpods, passive exposure via targeted ads has been one of the best ways for me to find something worth purchasing.

Sometimes ads do that. I recently had a purchase that I got a lot of value off of based on an Instagram ad to my partner. I would not have known about the product otherwise.

The issue is "sometimes" probably amounts to ~1% of the time, based on my made up anecdotal observations.
