Actually, that's an interesting idea. An extra travel option that costs gold, and reduces the chance of theft. Like hiring a one-time escort. Make it pricey, and not always available. 25 gold for a one-region move. Too much to use routinely, but perhaps there when you really need it? Shuffling gold across the continent, say 12 regions away, would cost 300 gold.
The lowest-income class should have to pay ten times more than the normal-income class just to get the same protection?
