WHY ARE CONSERVATIVES MORE IMPORTANT THAN LIBERTINES?
Because given moral justification to correct violations of purity and sanctity a sufficient number of conservatives will use violence to restore order. Only conservatives act for social good alone. Libertines and progressives act only in their self interest. Why? Because libertinism is purely a status seeking effort, and progressivism is both status seeking and dysgenic.

WHY ARE LIBERTARIANS POLITICALLY IRRELEVANT?
Because political systems are constructed by violence. And conservatives are willing to create an order that suppresses consumption in order to construct commons, and progressives are willing to use violence to destruct an order so that they can increase consumption. But libertarians are both small in number and unwilling to use violence.
Violence raises the costs of non-cooperative action, so that cooperation is preferable to non-cooperative action.
Libertines always look for discounts (freebies). There aren’t any. Order is expensive.
For these reasons libertarians will only exist in absurdly wealthy periods of history, made possible by conservatives. Otherwise they will exist only as another rejection-cult, criticizing the fact that they are required to pay costs for norms that do not improve their status – but constrain it.

WHY DO LIBERTARIANS ALWAYS LOSE?
Libertinism. Meaning incorrect attribution of legal, economic, political and military value to costs of high-cost, high-trust norms. Conservatives do not make this mistake – if anything they over-value norms. Libertines discount norms. Progressives never even consider them or find prohibition on their consumption antithetical.
