It's of no use when defined by the same person. It's of immense use when the user gets to decide which resources are to be used, and the operating system enforces their will.
Wallets/purses/etc. work because their user can see their cash, and quickly decide which economic capability tokens ($5 bills) they can dedicate to a financial transaction. (I.E. buying a loaf of bread) There's no chance that giving someone said token will compromise your email, dump all your passwords to utopia, promise your first born son, etc.
