It's possibly a safety concern. With paragliding, which is largely self-regulated by the USHPA (FAA airspace use regulations notwithstanding), I don't believe you can technically take payment for a tandem flight unless the passenger is a student pilot, at least on paper.[1] IIRC, this is to discourage pilots with a tandem rating taking undue flight risks to make money on giving rides.
