Freedom from Sanity
This seems to presume that our interests will never be in conflict, because we will never compete over the same scarce resources, both premises that I would have to reject.The idea behind the invisible hand is that you look after your best interest and I look after mine and we both understand that each is doing the same. So we come to an agreement which works for both of our best interests.
The trick is to make the government concern itself with my interests, hence the need for collective action.If you feel you are not able to see to your own interests, then you might feel the need for the government to step in to look after your best interests for you.
The problem with that is, IMO, there is no guarantee the government doesn't have an agenda, that may not concern itself with your interests.
There is no guarantee that you and me will ever find common ground. There is, in fact, no guarantee that you will not take everything away from me and turn me into your slave, and you might have in fact a strong incentive to do so, in order to remove pesky competition over scarce resources while simultaneously gaining acces to a valuable new resource in the form of human labor.So me and you, we should be able to find common ground. Me, you and the government, there's no guarantee that either your interests or mine get served and the government gets to enforce its agenda.
