     (b) A municipality or county, including a home rule unit, may not regulate individuals and entities engaged in the business of collateral recovery in a manner that is less stringent than the standards established under this Act. To the extent that any regulation by a municipality or county, including a home rule unit, is less stringent than the standards established under this Act, it is superseded by this Act. This Section is a limitation under subsection (i) of Section 6 of Article VII of the Illinois Constitution on the concurrent exercise by home rule units of powers and functions exercised by the State.
