This would also
cut out a great deal of the cost of funding paying for all the collections, payments, debt recovery etc. associated with it.
Closer to ability to pay, and spread across more people reducing personal cost, and fairer in households with more than one taxpayer (as it's a household tax not personal)
I am up for this on one potentially significant caveat that it does not increase government interference with the delivery of the service, and further that government does not stich up the BBC with paying for infrastructure that's nothing to do with their offering or strategic aims...i.e. rolling out digital etc.
