No, it's like saying that the government shouldn't search every passenger boarding a bus, truck or vehicle to determine if they're carrying something dangerous, but should let the bus company, the trucking company, and the drivers of private cars decide (a) who gets in their vehicle, and (b) what they can/can't bring.

Example: I don't let passengers smoke in my car. I consider it dangerous (to my health.) That's MY decision. If YOU want to let people smoke in YOUR car, that's YOUR business. We don't need the government to create a rule about smoking in cars, or enforce it.
