People define
their utopia as whatever society doesn't have the problems they imagine,I defined it as (a) guaranteeing food, clothing and housing; and (b) where people are not compensated for their actions. This is an abstract model of a functional society that might exist without capitalism, and it's not subject to my whims.
If you believe such a society is impossible, or prohibitively difficult to get to, that's one thing. If you have reasons that such a society would be a bad place to live, then that's a different thing: it means we shouldn't be striving for it, and that's a really valuable insight! Both of these are ways you can productively argue with anti-capitalists, and I wouldn't say either kind of criticism is stupid or boring.
Such criticisms might be obvious to you, but they're clearly not obvious to good-faith anti-capitalists (of which there are many, though you might not meet them much on internet forums). If you can only share your insight, maybe you can turn those good-faith anti-capitalists away from their path of pointless, desperate futility.
> In utopia bad things do not happen.
I think you're thinking of eutopia (lit: good place). I said utopia (lit: no place). "Magical utopia" was a deprecating caveat, referencing the uselessness of this description as an instruction manual: if that part is confusing you, feel free to ignore it.
Compare the magical utopia presented in Cory Doctorow's Down and Out in the Magic Kingdom, where food, shelter and immortality are available unconditionally to all citizens of the Bitchun society, and everyone else is dead. That society is not a mere happy fantasy land: it has problems, and those problems are consequences of how society is organised. The Clarketech that supports the society might be impossible, but saying "that society's impossible, so thinking about it is irrelevant" is just a refusal to engage with the premise.
Frankly, if you don't want to have an opinion, then don't have an opinion. If you don't want to explain your opinion, don't explain it. But don't state your opinion, and then act like explaining yourself is beneath you.
