You keep saying this, without ever explaining what is not "solid" about minarchist legal theory.
Or what objection to it we minarchists are supposed to be answering.
There is literally zero content to what you're saying, nothing to respond to. You might as well make fart sounds with your mouth.
Your reading skills fail you. This is why you
think there is no content in what I wrote. I said constitutionalists don't have a legal theory
at all(much less a sound one). I believe it was CCTelander who once aptly called it "bullshit on stilts". I was hoping I wouldn't have to be so blunt with you, as that's condescending and patronizing to the average or above average schooled person, but I guess I do.
Now, I imagine you're asking yourself "what is this 'legal theory' thing?" Glad to answer!

Now you have the general ideal of legal theory (theory of law). Below is an example that makes it even clearer.
The Pure Theory of Law
First published Mon Nov 18, 2002; substantive revision Wed Jul 7, 2010
The idea of a Pure
Theory of Law was propounded by the formidable Austrian jurist and philosopher Hans Kelsen (1881–1973). (See bibliographical note) Kelsen began his long
career
as a legal theorist at the beginning of the 20th century. The traditional legal philosophies at the time, were, Kelsen claimed, hopelessly contaminated with political ideology and moralizing on the one hand, or with attempts to reduce the law to natural or social sciences, on the other hand. He found both of these reductionist endeavors seriously flawed. Instead, Kelsen suggested a ‘pure’ theory of law which would avoid reductionism of any kind. The jurisprudence Kelsen propounded “characterizes itself as a ‘pure’ theory of law because it aims at cognition focused on the law alone” and this purity serves as its “basic methodological principle” (PT1, 7).
now you know enough to go to the library and start working to make Constitutionalism rational and practical.

Future generations of Constitutionalists will thank you if you manage to pull it off.
You're most welcome! Glad to help.
