That is great in concept, but I think it is unlikely to work on a macro scale.

Humans evolved as herd animals which instinctively gather in groups for safety and cooperation to insure better survival rate. Despite humans coming out of the bush and building large cities, our evolved animal instincts are still active and working to influence our behaviors. Humans are still instinctually driven to belong to groups, which is why religions have lasted as long as they have. Our human instincts manifest (mostly) as emotions, which is why people often choose to make emotional decisions over logical decisions. We are hard wired to follow our instincts and driven to make decisions based in emotion, which is a manifestation of instincts which we evolved for survival while humans still lived in the bush. Of course those of us who use computers and digital devices no longer live in the bush, but we have not evolved new instincts to deal with living city lives.

Anyway, some of us can adapt and train ourselves to live as individuals, but the vast majority of humans are still emotionally driven, and succumb to the instinctual drive(s) to belong to groups, as if makes them feel safe and secure to belong to a group who (appear to) accepts them. Thus religions flourish.
