It's not pragmatic, it's dangerous.
Sooner or later someone could take control of one of the accounts you don't care about and use in a way you don't expect to gain control of things you do care about.

An example would really drive your point home. Can you provide one that people would deem "dangerous"?
Edit: ccooffee just mentioned in the thread that you could be de-anonymized by reusing the same password. Is this what you mean? There's a spectrum of comfort with privacy so maybe that's the source of the disagreement between whether it is important to have unique passwords or not for accounts that don't contain financial/SSN/medical/etc information
You might not care about what's contained in a certain online account, but there could be utility in taking control.
Strong and unique passwords for the important accounts, simple and reused passwords for the rest. You're welcome to hack into my accounts on Hacker News, Reddit, Discord, LINE, various IRC networks, various forums, etc. I don't care; there's nothing important in there besides sentimental value.
I'm now firmly in the "everything gets a unique password" camp. There are 4 important passwords I type myself, but everything else is in a password vault.
