(a) [When security interest not invalid or fraudulent.]
A security interest is not invalid or fraudulent against creditors solely because:
(1) the debtor has the right or ability to:
(A) use, commingle, or dispose of all or part of the collateral, including returned or repossessed goods;
(B) collect, compromise, enforce, or otherwise deal with collateral;
(C) accept the return of collateral or make repossessions; or
(D) use, commingle, or dispose of proceeds; or
(2) the secured party fails to require the debtor to account for proceeds or replace collateral.
(b) [Requirements of possession not relaxed.]
This section does not relax the requirements of possession if attachment, perfection, or enforcement of a security interest depends upon possession of the collateral by the secured party.
