First of all, it's a volunteer military. You are not required to join, and you know what you are getting into when you do. Second of all, what you are essentially suggesting is a private military (one where people come and go as they please and pay is at the market rate). That's certainly an option, but after seeing the results of other privatization schemes that one might consider similar, say the use of security contractors or private prisons, I'm skeptical.
