In local system yes, but in production its painful to work with. With RVM for isolation you would create gemsets for each app with specific ruby version. It OK for 2-3 applications, but anything more than that would be a pain to work with. And then if you plan to put everything behind passenger, it would just be too messy. Think of automating this? Would be a nightmare to maintain. Over here containerization does help.
