In the bitcoin world, when you transfer your dollars, goods or services to someone all that has happened is numerical marking of the transfer. That is all. After the transfer you didn't become the owner of some right, claim, good, service, etc., but a visible trace is created in the database that you gave something for nothing. In the real world, when you transfer your dollars, goods or services to someone, this can also be marked numerically, for accounting/bookkeeping purposes for e.g., but you will also receive something of the same kind in return - euros, rights, claims, goods, services, etc.

So the only information attached to bitcoin is mark of the fact that you gave something of value and received nothing in return.
