Like actually because this helps people from being Machmir on things that are dangerous to be machmir on.
No it doesn’t. Am haaratzus can (and has) caused problems both ways.
I don’t want to get into details (same sensitivity as Oomis), but I know a case where a yoetzet halachah was machmir based on blatant am haaratzus and stupidity (US story). Of course, Sam says they’re not supposed to pasken, but that didn’t stop this woman.
