EULAs appear before installation (the actual transfer). That's why you have to offer refunds to those to disagree with EULAs.
Transferal of goods or valuables, ie. money, happens already at the store.
Ownership of a piece of software is no more transferred than ownership of a song or a story is transferred when you buy a CD or a book.
You are mixing up concepts of ownership and copyright. They are not the same thing and should not be mixed; you own the copy of the book if you buy it and may do with it as you please, but the original author still holds copyrights to it and thus you are not allowed to break copyright law. Do NOT confuse these things.
What rights have been lost? As far as I know, selling things you don't legally own is a crime, not a right.
