Apollo was largely driven with the purpose of achieving the goal rather than obsessing on the details on the way to that goal. In fact during Apollo they even completely scrapped mathematical risk modeling because the results it always gave were basically 'you die.'
So for instance a relevant and famous anecdote is that the original tests for Apollo launches didn't have any sort of urine/fecal disposal systems at all. In one delayed launch during testing Alan Shepard was in the capsule for hours and ended up needing to go pee. He asked for permission to depart the capsule, but that was declined to keep it all on track. So he ended up having to just pee all over himself in the suit.
Another piss poor anecdote is Buzz Aldrin on the Moon! When he departed the lunar lander capsule, the impact ended up breaking the urine collection device inside his suit. So his journey on the Moon involved having a healthy dose of urine sloshing around in his boot where it settled.
Of course there's a balance in all things. It's not like they just YOLO'd their way to the Moon. But things where the worst case outcome would be astronaut discomfort were seen as extremely low priority. In the original design, the capsule didn't even have a window or manual controls. So the astronauts were basically just being treated like human Laikas. They had to fight just to get those 'features.'

I think a big part of the reason for this is because there are basically infinite things that can go wrong. And so if you obsess on getting every single thing right, you'll end up never doing anything at all. In 1962 Kennedy gave his famous 'to the Moon' speech. At that time, we'd only just barely put the first man in orbit but had never done anything beyond that, at all. Just 7 years later a man would walk on the Moon. In modern times we've been basically trying to recreate what we did in the 60s, and spent decades doing so. And this obsession on the details is certainly a big part of the reason why.
People joke about "safety third" but I've always thought that was literally about right. It's a higher priority than many other considerations, but it's no way the highest priority. Doing or having something at all absolutely comes before having it in safety and comfort.

I've had a similar conversation with the "but if we really went to the Moon in 1969 why has it taken so long to be able to do it again" folk a few times.
The real answer is of course that we did it once, and realised that a project where about 99% of the failure modes are "astronauts turn into a rapidly expanding cloud of fried mince" and all of these failure modes are incredibly likely was not something we really wanted to do again.

In hindsight we know, that these models were wrong. people were better at predicting risks without relying on formal models. I mean, people were not perfect too, but still they were better. I wonder, if modern engineering has better tools for risk modeling and how good they worked if they were used for Apollo. I mean, if we remove the knowledge specific for space flight, leave only the abstract theory of risk modelling, and then use a time-travel machine to send it to NASA at 1960 or so, could NASA employ modern risk modeling tools to get results on par (or better) to human intuition?
