Well, this quote is from the movie adaptation, which strayed pretty far into statism compared to Heinlein’s book treatment.
Still a good quote.

You're right. I'm not sure how the movie quote made it into my collection of quotes, but somehow it did. I barely remember the movie. Here's the quote from the book. They're pretty much the same message.
"To vote is to wield authority; it is the supreme authority from which all other authority derives -- such as mine to make your lives miserable once a day. Force, if you will! -- the franchise is force, naked and raw, the Power of the Rods and the Ax. Whether it is exerted by ten men or by ten billion, political authority is force."
“Violence, naked force, has settled more issues in history than has any other factor, and the contrary opinion is wishful thinking at its worst. Breeds that forget this basic truth have always paid for it with their lives and freedoms.”
“Liberty is never unalienable; it must be redeemed regularly with the blood of patriots or it always vanishes. Of all the so-called natural human rights that have ever been invented, liberty is least likely to be cheap and is never free of cost.”
