Companies that offer "free" services in return for your personal info

Proposal for discussion: Companies that offer "free" services in return for your personal info ought to be required to (a) refer to their services as something other than "free", (b) put a dollar value on your information, (c) allow you to pay that amount instead of giving your information, (d) report your information & dollar value as "revenue" when filing their taxes. Governments are missing out on a huge amount of tax revenue by failing to recognize that the information we provide to these companies has value. Grocery store loyalty programs, Facebook, Gmail, Google Now, etc etc. Perhaps this could also have the side effect of educating consumers about the value of their personal information, and just what it is exactly they are giving away in return for these "free" services. Thoughts?
