Re: Pricing them out of existence
The whole thing smells of confirming the answers some group wanted to hear rather than anything genuinely resembling a survey.
Similarly, the "public's" solution of a registry sounds like bollocks to me. Presumably there would be a fee and coughing up personal details to a government department, thereafter to be hacked and posted on Pastebin/sold on dodgy forums. Plus people who are planning shenanigans aren't going to register anyway. People like myself who don't have shenanigans planned but like to keep their options open aren't going to register unless there's a spectacularly good reason for doing so.
Usually the only thing registration solves is a government department's shortage of tenners.
