That is exactly the point OP is making. If you do not have a mandate to govern from the people, you need unanimity from all homeowners. Those are the alternatives.

You don't strictly need a mandate from the people; authoritarian governments can be legitimate despite not having such a mandate. However, it's an impossible trilemma: successful action needs at least one of unanimity (parent commenter's approach), threat of coercion (government), or tolerance of free-riding (charity).

		Why would you leave out the form specified by the GP? Representative (republican) government where the 40 members would hold an election to nominate a smaller number of representatives to decide on what should be done and bind everyone to abide by their decisions. If you require unanimity then everyone has veto power over every decision which is difficult to manage even with 40 people. If you select 5 or even 3 people out of that group of 40 then it become much easier to make a decision. If everyone can nominate and vote for their representatives then they should feel it is fair when they have to abide by their decisions. At such a small scale you have very direct access to your elected representatives so you should feel that they have heard everyone's opinions and will hopefully do their best to accommodate them and if they don't then you should not elect the same people again. At this scale you really can't call it threat of coercion, the land isn't owned by a separate entity so individuals could choose not to participate and all participants have direct access as well as a significant weight to their vote. It is a self-binding agreement if you choose a representative.

There are plenty of other alternatives. Where do you think organized crime came from?
