I don't think any domain registrar will willingly not do it. There should be some kind of law, that makes this practice illegal - both the registrar doing it themselves, and giving the data to others so they could do it. In fact, there should be a law prohibiting the sale, sharing or even saving of this data completely. If I search for a domain at a registrar's site, that shouldn't be logged anywhere.

Not directly related, but - it would be nice if there is a law that says "any domain name can be sold only for a maximum of 10 dollars" - that would prevent the disgusting domain squatters. It would upset those who spent millions already, but it might have some affect on the future squatting of domains.

Um, no. That's not true. Sending armed men into your competitor's retail store to trash the place and scare off customers is not "fair". This is also why, among other reasons, it's illegal.

Commerce is one of the many mechanisms by which we collaborate in making a better world. If you have found a way to abuse that mechanism to enrich yourself at the expense of others, then you're an asshole.

That you can get away with something for a while does not make it right, and it does not make you less of an asshole. Indeed, I'd say that finding a new way to fuck people over, and therefore forcing the creation of a new regulatory apparatus that burdens us all, makes you more of an asshole.
