The overwhelming majority of people want to use government taxation to fund the military because they believe it is the most efficient way of providing defense for the nation. More efficiency implies that people have more money and therefore more freedom to do what they want. And more freedom implies less coercion.

If a libertarian proposes using anything other than democratic means to end government taxation (that supports the military), he should be jailed because such a proposal could only be implemented by using violence to contravene majority preferences.

Therefore the only morally defensible and consistent position for a libertarian is to favor gradual democratic change. Since the public thinks it is less coercive because it is more efficient to utilize the government to fund a sufficiently powerful military, essentially noone except a radical libertarian will favor eliminating our publically funded military.

Until libertarians can demonstrate that we can obtain a private army with the strength and power of the United States military, but by spending less money, citizens will continue to favor utilizing government taxation, unless a libertarian is prepared to coerce everyone else by overthrowing the government.

Therefore, libertarians must logically favor utilizing democratic processes, if they do not wish to be coercive.
