People make irrational purchases all the time and I don't really see a problem with that. What makes me wince is when people are trying to rationalize their irrational purchases, especially with strangers. Or when strangers seek to make them feel silly or bad about it.
My hypothesis is that irrationality is economically inefficient at a macro scale; dollars flowing through manufactured irrational purchases get centralized into Apple’s coffers to be directed via their inefficient centralized decision making.
This hypothesis of course may be false - maybe Apple is better suited to take those irrational dollars and deploy them more rationally.
I think the issue with the irrationality is that it isn't random. If some people made a mistake 20% of the time, completely randomly, when deciding between two products, it doesn't matter too much, and the dollars flow to the person who trembles less. However, humans can be exploited to make more mistakes. Gambling companies are a clear example, but I think run-of-the-mill advertising optimizes to be exploitative more than informative as well. Thus, all the dollars get sucked in by people who are actively anti-social, instead of those that offer a better product or make fewer mistakes.
(1) makes companies market (lie) more aggressively, because it ends up working out.
(2) makes prices irrational, because if a bunch of stupid people will buy your shit product, why would you care about the 1% who actually do their research?
(1) But that's how commerce works. Does a product sell? Okay sell it more.
(2) People who "do their research" aren't entitled to anything. Maybe they just won't buy it? Then it's not for them. I don't understand what "makes prices irrational" would even mean in this context. The right price is whatever maximizes P * Q.
(1) You don't see the problem with people who are better at manipulating and lying to others through deceptive advertising getting a bigger market share? That's just so obviously bad for society.
(2) Suppose you need insulin to live, but it's suddenly become a meme to start snorting insulin and all the stupids make the price shoot through the roof. That's what stupid people "making prices irrational" looks like, and it happens with fads, or inferior products, or even allowing actual scams to be posted in online marketplaces. Happy smiles on paid actors should not be enough to make your product more appealing than your competitors', and yet the stupids will drive out of business people who don't engage in such pathological behavior.
