Static label assignment is tremendously onerous. Keep in mind that without a control plane that has some topological awareness, you'd need to configure label in/out relationships on every transit router in your network, per LSP. Try that with 5000 LSPs :) I'd rather do 5-10 in a low security prison myself.
