It can, though. In a lot of the interconnected LARP orgs, stuff can happen like it might on a MU*, though not all of it might be linked to one city. However, I agree; there are a lot of things that MU* need to account for that LARP won't by default (it's been one of my challenges using MET:VtM, particularly in how feeding and blood mechanics work in it).
I think picking and choosing the best options from all, or making logical extrapolations works out well, though many probably need fine-tuning once seen in use (for example, if you have a Feeding Downtime, you come into game at full Blood; my logical extrapolation of this is 'if you have a Feeding Downtime, you spend time here and there getting a nip, and you get <X> blood to draw from for a particular period'.)
