Monica.....when I think of your "intentional communities" I am reminded (a bit ) of some friends about 30 years ago in our parish who formed some sort of prayer and study group that is still going strong ..meets in homes several times a month....currently the members are really old so there is a lot of "help and support" going on....but these were the guys buying the Vat 2 experts books etc...back then, really well informed..and very good friends....

It's the only vibrant example I can think of ....as opposed to that "50 minutes on a Sunday", quick in quick out "normality".

I am inclined to think intentional and supportive communities are a fine idea!
