First of all, one important rule of democracy is that you cannot vote about stripping someone's right in democracy (or alternatively, the democratic decisions have to be reversible), otherwise you will get Russell-style paradoxes. The existence (or not) of democracy itself cannot be decided democratically; this is often neglected but nevertheless important rule.

Second, your example is unrealistic. There are far less wolves then sheep in the real world (literally!). In the real world, this is not really a big concern, because you wouldn't want to live in society where are more wolves than sheep anyway.. Almost every social technology (including evolved human cooperation) is predicated on this being false.

Of course, there are other things that are important for society and orthogonal to democracy - as you mention, for example, rule of law. But I disagree with rule of law you're safe from government actions - the state is typically the actor who enforces the law. So I very much disagree with the sentence "Rule of Law gives you a safe life (at least from governmental actions)." I would like to see an example of society where this is true due to it not being democratic; since democracy effectively gives you control over government actions.

I don't buy the idea that there are no free resources in the world. It seems very obviously false, it seems isomorphic to labor theory of value, and leads to logical contradictions (such that value is not monotonic in effort). At minimum, there are other actors in the world that produce value; take for instance a hen producing an egg. The egg is valuable and is produced by the effort of the hen (scavenging for food). Yet we cannot assign this value to any person, it just comes for free from nature.
