ahh wait, this breaks DRep registration...
let me fix

[Ryun1]

There is an edge case where a user has a UTxO with 501 ada and they try to register as a DRep
And this 501 UTxO gets (randomly) selected to be used in the transaction
The transaction will just balance itself to have that one input, resulting in a fee paid of 1 ada (and no outputs created)
