While you are right that data like your address is freely available it should be mentioned that data like your income is a bit more ”protected”. One has to pay for it (and AFAIK there is a limit on the number of items a private person can buy) and the person whose data is queried is notified about such query (who asked what). Also some info is not so detailed as it may seem first. What does it give you if I say that I own a Volvo in the country where 30% of cars are Volvo? EDIT: spelling
