In an ideal version of reality, how do you want the sellers of this product to let you know that it exists and you can buy one?
I guess the flip side to this question is; how do you ever know someone wants to hear what you have to say? Isn’t society one big collection of unsolicited messages?

Advertising is art with an ulterior motive for existing. As long as we’re not being openly lied to, I don’t think it’s bad exactly, but in a world where there are important things to do, I would suggest it’s probably doing more harm than good.
