Or I just don't particularly expect laser accuracy on a $300 piece of plastic, and think it's a bit ridiculous to get a tizzy fit over something you wouldn't notice if others weren't getting worked up about it. Sure I'd like to be able to put a ruler to it and not have a 1-2mm deviation, but not if all consoles would cost $350 as a result. To me these 'nonsense complaints' lessen the actual problems, like joycon connectivity and bent docks.
Come on, a bent product (even if by a few mm) is a nonsense complaint? People care about aesthetics, they care about something they spend a lot of money on being high quality.
Trying to diminish it by saying it's a $300 "piece of plastic" is really weird, do you think Nintendo or any of its fans see it as such? When people design products a lot of thought and care (typically) goes into that and I assume Nintendo is the same, thus I assume they care when people notice that their product is bent.
The last thing I'll say is that people often come into complaint threads saying stuff like you did here:
"think it's a bit ridiculous to get a tizzy fit over something you wouldn't notice if others weren't getting worked up about it"
My problem with this is that it's all concerned about tone, which is impossible to get right on the internet. Even when people are just complaining or criticizing about a minor problem it's often construed as them being outrage, or as you put it, in a tizzy fit. Why are all complaints and criticisms perceived this way? It is possible to have a minor level of dissatisfaction compared to those larger issues you correctly highlighted. That doesn't mean we have to completely shut up about it. Problems will naturally sort themselves by order of magnitude as long as people don't try and shut conversations down.
