Re: What planet?
Governments used to sell our names and addresses from the electoral register. Then somebody sued and won.
So now we have the real register, with all entries, for use by government and by political parties and candidates. Then there is the commercial register, containing only those who have not opted out, for sale to anybody.
We need a similar scheme for other data, with an additional requirement. Everybody is entitled to be individually paid 50p or whatever for their data, and the costs of those payments must be borne by the purchaser of that data.
