No, murder is not comparable to advertising. And no, not once did I ever say the phrase "self-regulating" nor did I argue against regulation of advertising.
Your fundamental belief (and the prevailing view on HN) that advertising is a scam and intended to "misinform" is incorrect. Apparently I need to say this again because it's hard to grasp the concept of nuance--Are some advertisements scams? Absolutely. The market is not perfectly efficient, but again, markets trend in the direction of efficiency over long periods.
Ultimately, the vast majority of advertisements you see are for the products that are the most desired by people, hence why they can profitably continue advertising over time.
Just because you aren't interested in the product, doesn't mean it's a scam . Enough people in the audience of whatever media you consume think otherwise, hence why the company is advertising there. Again, there are absolutely stupid companies wasting money on stupid ads, but they tend to get outcompeted by the smarter ones. I get it though, giving people you believe are less intelligent than you the freedom to make decisions is frustrating.
Even in your example of the slap-chop, which you say is a "worthless product," funny enough, I literally just used a similar product yesterday to dice a large amount of onions quickly. Guess I'm stupid and I need an authoritarian like you to tell me a smarter way to live.
Alternatively though, the idea that knife makers don't promote their products is just hilarious to me. The market for kitchen knives is extremely competitive and just because the advertising doesn't take the form of a 30 second TV spot from the 1990s doesn't mean they just throw their products on the market with zero promotion. How do you think certain brands even appear on the shelves of the stores you shop in? You're gonna hate this too...turns out shelf space is scarce so shelf space is a market as well, and it's more of an economic calculation than one of technical passion. Oh no not again!
