So, you can take someone for a ride, as long as you aren't paid more than an equal share of the expenses.
So there ya go. Don't think anyone would try to get rich, but if they object to the amoeba like spread of government snooping, they may well be willing to split expenses.
From the TSA site. Too bad they aren't this sensible in commercial aviation:
TSA issued a Notice of Proposed Rulemaking (NPRM) in October 2008, that would strengthen the security of general aviation by further minimizing the vulnerability of aircraft being used as weapons or to transport dangerous people or materials. The proposed regulation would reduce the susceptibility of large aircraft misuse by individuals wishing to harm the United States and its citizens.
The Large Aircraft Security Program (LASP) regulation would require all U.S. operators of aircraft exceeding 12,500 pounds maximum take-off weight to implement security programs that would be subject to compliance audits by TSA. The proposed regulation would also require operators to verify that passengers are not on the No Fly and/or Selectee portions of the federal government's consolidated terrorist watch list.
The LASP would require currently unregulated general aviation operations over a specific weight threshold to adopt security measures, which would align these operations with operations currently regulated for security purposes. TSA continues to enhance international and domestic general aviation security by developing a comprehensive strategy to:
Establish baseline standards of security for general aviation operations;
Ensure that flight crews have undergone a fingerprint-based criminal history records and terrorist name check;
Designate security coordinators;
Conduct watch list matching of passengers through TSA-approved watch list matching service provider; and
Check/validate property on board for unauthorized persons and accessible weapons
