0.1c isn't slow enough to solve the empirical puzzle that we don't now see alien volumes. That is the fact that pushes for higher speeds in our analysis.
If we've set the fine levels right, someone who can't or won't afford crime insurance is a net liability to the rest of us. The insurance premiums will vary greatly with the conditions one agrees to. Very few people would be unable to afford any such conditions.
I did say explicitly that the one exception to fines as official punishment is failing to arrange for insurance. Your contract with an insurer can specify the court that judges disputes with it, and the forms of punishment available there.
Bounty hunters exist today, avoid shootouts, and are well enough trained when that happens. They would have no special powers, and thus be liable for any damages caused by a shootout.
As many have long expressed this concern, I and others have long done research into "manipulation" of prediction markets. We've done theory, lab experiments, and field tests. We find prediction markets are especially robust in resisting such influence, compared to other institutions and mechanisms.
So it seems that you think that while anarchy would better achieve a true national welfare, it would not do so for any concrete concept of national welfare that one could define and measure. True welfare somehow is intrinsically unmeasurable.
Putting in weights to directly favor specific policy proposals is very different from putting in weights to penalize the kinds of means that people dislike. For example, if we dislike police detaining folks without charging them with a crime, we could count such events and penalize them.
It sounds like you think that while you like private law and anarchy, you don't think that it would actually achieve the ends that most ordinary people want to achieve. And you think speculators will agree with you, and in a futarchy would therefore reject anarchy proposals.
You are talking about the issue of manipulating prices via trades. We have lots of evidence that this isn't much of a problem. Read my papers for details.
