So, Block is taking libertarianism to its logical conclusions? If not, what is he getting wrong?
There is a difference between saying, "Government's proper role is to do X and nothing more." and saying, "Government has no proper role at all and everything that it does is illegitimate."
I don't think the second statement is necessarily a logical extension of the first.
I have always wanted to ask this
How much is enough?
How much privatization is enough?
When will govt be small enough to drown in a bath tub?
Why does government exist? There was a time when it was felt that a primary role of government was to protect the established religious institutions of the society. Do you think that is a proper role of government?
So if you accept that there are some things government shouldn't do, you are in favor of limited government. If not, you are a totalitarian.
Then there's a question of what the government is capable of doing. For example, should it outlaw drugs when, in fact, it cannot even keep them out of the prisons where it locks up the drug offenders?
So now you have two issues. What can the government legitimately do? and What is the government competent to do? And when you strip it down to these basics, you find out that government can't do very much whether you want it to or not.
Should the government guarantee a certain wage? It can't unless you want lots of unemployment. So now we'll pass a law guaranteeing employment? Good luck with that. The government would have to tax the people to death to pay for it all.
A society, including, but not limited to, an economy, cannot be run by decree.
We need government to protect us from foreign domination. We need government to protect us from neighbors who might be too aggressive, and we need government to resolve domestic disputes.
Do we need government for any other purposes? What kind of benefit is it for government to tell me that I have to purchase health care? How have I benefitted from the government telling me that I must pay into a retirement plan? I can do those things without government. So the only point of these programs is to protect me from myself.
What if I don't do them, and I die or end up as a homeless beggar? I become a victim of my own behavior. So would it be appropriate for the government to assume the role of a charitable organization and take care of me? Perhaps. But that is a far cry from cradle to grave welfare and, historically, was a role for state and local governments in America not for Uncle Sam.
Likewise, in a complex economy such as we have today, people can become victims of circumstance. Depressions, recessions, inflation, stagflation, etc. So what should be do about it? Aside from a few social programs that have historically been the responsibility of state and local governments, the government has proven time again that it is incompetent to run the economy. All of our interventions make matters worse.
So why does the federal government need to do anything beyond its original mandate? What is the advantage of the federal government getting involved in all kinds of problems that it is incompetent to handle? And why on earth do we think the federal government is competent to handle these problems and more in Afghanistan or Syria or Ukraine?
When you insist that the federal government is legitimately empowered and also competent to handle any and all problems of society, you are asking for totalitarian government. You are denying your own capacity for self-government and the capacity of any other human for self-government and therefore we all need to be governed by OTHER HUMANS who are also incapable of self-government but are somehow capable of governing us.
