The town (the preferred AH3 "defense" of the current insta-gotta-have-it-now gamer generation) already gets resupplied fast enough.
Now just a minute,when exactly was Fast Food invented?
McDonalds 1955ish
InstaBurger King (now known as Burger King) 1953
Kentucky Fried Chicken (NKA KFC) 1952
I think Insta-gotta-have-it-now is a bit transgenerational.
I'm not sure when the supply mode changed, it seemed like it didn't exist as the super town rebuilder. It did change didn't it? I just figure people do what people can do with what is available, I'm not banking on self restraint in a video game, it hasn't worked for me anyways.
