Hm. I wouldn't say I fully disagree, but while I'd say there is a gradient in personalities from people who are compulsive rule-followers to the oppositionally defiant, I think in practice a lot of people manage to compartmentalize breaking a particular set of laws without being generally lawless. e.g., buying marijuana without a tax stamp, taking pay in cash under the table, downloading copyrighted material without paying for it, and so on. On the other hand, I wouldn't expect the riders in your example to be wearing proper PPE or have the proper registration, permits, and so on, so I think we can say they're "generally scofflaws" if we restrict ourselves to laws involving ORVs.
I'd put it a slightly different way, although maybe we're both going after the same point here: if riders don't feel that they have any obligation to respect public land or the law, it's pointless to argue about ORV parks or carveouts to take off the "pressure" because they don't feel any pressure; they're going to ride in the woods, regardless, when they feel like it until caught and punished.
