Yes, the users 'pay' for the services they value by providing data. But if data has inherent value (like oil) then transaction should be taxed somehow. Then sales (the monetization of the data) as tax base or allocation criterion could be a way of doing that?https://twitter.com/MForstater/status/953901680164294656 …
Im not sure it is really true that data or oil have intrinsic value - it depends where it is and what you can do with it (philosophical answer - in practice u tax whatever u can!)pic.twitter.com/Iu66IhQGpa
