This is FUD. Cast iron seasoning has been mythologized, it's not that hard to maintain good seasoning. Even if you wash with some soap.

To be fair, the vast majority of people I've lived with or know-well-enough-to-know-this-about-them (we need a word for this concept in English) can't be arsed to clean their pans immediately. Especially those who rely on a dishwasher.

Cast iron isn't compatible with that approach.

You have to be the type of person who can appreciate and capitalize on the fact that cleaning off eggs immediately after cooking takes 1 second while chiseling them off tomorrow can take 5 minutes.

Yeah, I don't consider a meal done being prepared until the counters are wiped down, everything is put away, pans are cleaned, and it's plated for everyone.

Part of why I do this is because I have 3 kids. They are off playing while I cook, and I take the extra few minutes to get the kitchen in a decent state before calling them to the table. Otherwise I'm never gonna get it done because once they have my attention it's difficult for them to let go of it.

I use my main pan daily, but I've also never had an issue pulling out my other pan after it's sat for a month or two and just using it. A really good seasoning helps with long term storage too.
