"Free State" doesn't necessarily mean a particular geographic or political entity:
noun: state; plural noun: states
the particular condition that someone or something is in at a specific time.
"the state of the company's finances"
synonyms: condition, shape, situation, circumstances, position,
"the state of the economy"
a physical condition as regards internal or molecular form or
"water in a liquid state"
(there's more, but this is the important part!
So, "the security of a free State" means the preservation of a condition of Liberty.
Put that in your crack pipe and smoke it, grabbers!
Freedom is my Worship Word!
