Supporters of the theory of real right behavior believe that the most important value or function of the theory of real right behavior lies in protecting the security of transactions.

They pointed out that the meaning of the party as the cause must be separated from the "component" of the ownership transfer, otherwise the new owner will be attached to the original acquirer, and it is difficult to avoid the possibility of losing rights due to the defect of the cause relationship. In this way, the transaction will be hindered.
