However, you took this sense out of context: the context is "There is something worth non 0 value of living in a society who accepts you despite being sick or 'dirty', and is willing to take the risk of having those who are tainted amongst them. I feel that's an attitude that comes from a place of strength not weakness."
This is much more nuanced. Nobody should be forced to do this! And after all, it's someone's interpretation. The OT specifically instructed people for such diseases as you might know. Christ helped the sick not naively, but knowing he can heal them. Doing things naively is not always good.
The picture you draw sounds like a strawman of catholicism. Well, "The heart is deceitful above all things" says Jeremiah: our flesh is very proud and letting the ego go is extremely hard for it. However this is more similar to the frustration of a child wanting to create it's own society far away from parents and then going and living in the jungle in utter helplesness and self-delusion.
There is a paradoxical beauty in the eternal which is hard to even articulate and those materialistic arguments ring hollow. I can totally see how it might look like that, but I'd say it's a look from someone who haven't yet actually tasted the beauty of Christ and the faith, see the peace in the Word or the saints. I've been in a boat similar to yours many years(and yes, you can have read the Scriptures 10 times and led 200 discussions, information is just information)
