> I wouldn't call collectors who act out of irrationality stupid since you have to look at the motivation behind a deal situationally — I'd just say it's on the edge of being an unethical waste of money.

Unethical? Huh? Ethics is concerned with morality; with right and wrong. There's nothing inherently wrong about paying large sums of money for beat-up bits of electronics. It's just plain ol' stupid.

One good reason might be if you think the value is going to increase beyond what you paid for it, like people paying whatever mad amount for bitcoins.

I think people who spend huge amounts on diamonds are stupid, but everyone has their reasons.

There are loads of ethical systems that condemn wastefulness of money; the US has had at various points at least a plurality, if not a majority of people ascribe to moral systems derived from puritanism, so at least in the US, it is unsurprising to hear someone saying that wasting money is unethical.
