I posted this in urbanism because I think it can be an offset for a nice discussion about living together in apartment blocks and the cramped conditions that arise, especially in sub-par block. Part of urbanism is urban living and discussions about how to tackle issues such as these.
Of course none of this would be an issue with good infrastructure, but that's something that can always be said. If everything was lollypops and gumdrops and so on.
I like the thread because both people start off reasonable and courteous and then end up calling each other names. I dislike it because, it being reddit, it just becomes a dogpile instead.
Oh, definitely not against having a second, fall-back bike! But if you're concerned about one of them being damaged, maybe address that first. Especially when someone has offered to pay for part/all of it for you. Doesn't work with the space they have in their apartment? Then rearrange what you can to fit it (at least one).
