I'm a lawyer, I earn my living by sorting out my clients legal problems. I also like winning cases. If I'm bad at my job they won't come back or pass on a recommendation. If I thought for one second FMOTL theories actually had any chance of success I'd advise my clients & run their cases in accordance with FMOTL jurisprudence. I've seen not one iota of evidence that any of this works. What I have seen is a bunch of so called 'freemen' who are completely focused on dodging paying taxes, getting their greedy paws on the mythical 'birth bond' payout (they'd do better to look for the pot of gold at the end of the rainbow) & getting a house for free with ludicrous attempts to redeem mortgages.
You never see 'freemen' articulate any ideas about dealing with societies problems (ie crime, family breakdown, child neglect etc). At least the current legal system trys to deal with these things. Why? As far as I can see freemen are fundamentally selfish, greedy individuals who are obsessed with the bottom line. They don't care about anyone else but themselves & the contents of their wallets.
