As far as just not shooting does, yeah, in theory it sounds good, but all you are doing is leaving a tag for another person to fill. The past two years I havn't bought a doe tag for this very same reason but they are getting bought up by guys who hunt the adjacent property and they do their deer drives and bust the does.
Not if your spending the 6.00 for the tag, What's 6.00 nowadays? I don't know the answers either ,but I will buy tags and not fill them if I have to.
