Interesting. Then the commandeering concept could or should also be applied by states and local governments being forced to provide social services to illegal aliens the federal government has allowed or brought in. From the definition, I'm wondering if states similarly have to enforce, for instance, civil rights laws, the ACA or any other federal laws without attached spending power conditions or directly compelling states to enforce federal regulations.

The Mayor of Oakland announced federal immigration raids to warn illegal non-citizens of impending federal raids. Intentionally undermining federal laws is a different category than federal government compelling states to enforce federal regulations. What other criminal groups get help from state governments? In some cases, illegal non-citizen criminals have been released and committed additional crimes and endanger federal law enforcement personnel.
