a lot of these people don't have that good of arguments, so they instead use crappy metaphors to make their points. they take something that is totally different than bitcoin and try to use that to make their point. but they need examine f it is a valid analogy. I don't think a PC, a consumer good, can be compared to something that's supposed to function as a currency. one is a store of a value and one has a functional use. if your grandma wants to save her money she should by stocks or bonds or something with low volatility. if she wants to send an email she should get a computer, not for storing value, but for it's functional use. and if she wants to get around town she should by a car, even though they depreciate. I don know how op ever thought it made sense to compare bitcoin and computers.
