The version of sovcit... ideology? lore? that I've seen goes something like:

• Because reasons, any time a US citizen gives birth, the US government is obligated to open a bank account at the federal reserve with $1 million in it, and keep paying interest into these accounts over time
• However, the way the law is worded only "natural persons" are allowed to access their account, and by signing your birth certificate you are actually a "corporate entity", not a person
• If you do these things and fill out these forms with these exact words and file them in this exact way and sign it with a blood fingerprint you can declare yourself not a corporate entity but a natural person, and access your account
• The federal reserve won't just let you withdraw cash from your account, but if you send a letter to someone who you owe a debt with this specific language on it, they can forward that to the federal reserve who will pay the debt on your behalf

Obviously this is all nonsense.

I'm imagining they are trying to pay their phone bill with one of these magic letters, and is surprised that whatever under paid corporate drone is running the collections team at T Mobile isn't in on the super secret conspiracy that only they are smart enough to uncover
