Not true, Catholic priests still have private property. But sure there are other religions that have this. It's voluntary and the percentage of people doing this is tiny.
Yes, it has happen that some people have given away all their property and secluded themselves. I'm afraid to ask what is the point of your question. You surely don't think everyone will give up their wealth to the avant-garde and submit to them voluntarily. You do know how many millions had to die because of such ideas?
