It may add some confusion... BUT it will be less confusing that tens of thousands of other coins out there all claiming you need a new blockchain & token to execute certain functions.
In general, bad ideas are bad ideas regardless of which platform they reside on. If there is a use case for any of these things, they will survive. I personally don't have a need for much of this stuff at the current time. Perhaps simple things like vouchers to redeem for products, event tickets, etc may have a place... but i dunno if it offers a markedly better experience outside of the status quo. The main benefit might be secondary markets without gatekeepers, but you still have to verify a token is actually linked to the real world thing it claims to represent.
This is a long rambling way of saying... I guess we'll see! I'll experiment as things come out
