Makes me feel more assured and will reduce my suffering until I die. After my death, regardless of if I am right or wrong, the net positive of having had the soothing idea of a larger meaning can’t and won’t be retroactively undone. So why the hell not?
Because religion can be and has been used to convince people to do terrible things. The fewer false beliefs people hold the fewer things can be used to manipulate them in this way.
we also don’t refuse to allow people to have small amounts of it accessible to them at all times or call it absolutely bad outright just because when used in a malicious way or left to be uncontrollable in particular situations it can be dangerous. shrug.
When doing risk analysis something that is required to keep people alive gets a few extra points towards being accessible for, hopefully, obvious reasons.
If even something that is necessary for life is controlled due to the danger it poses, you can imagine why people would seek to restrict dangerous things that people can live without.
