I think that everyone here has a big enough Q target on their backs without getting involved in Sovereign Citizen issues. There have been a number of Non Q FR Threads regarding this subject if someone wants to search for them.
If the FBI (And I am not saying that you are FBI) wanted to snag regular citizens as terrorists this might be a good way to do it. (See MI and G Whitmer kidnap plot)
Even if you do NOT file your 1040 as a sovereign citizen not subject to taxation you do not want to go to a seminar and end up on some federal "Need to investigate" list. Nobody wants to have FBI or Armed IRS agents showing up at your door to ask questions (Probably should not talk to them.) and then have to spend retirement money to hire an attorney because the FBI wants you to come down to the office to "discuss things".
This is essentially the Governments position on this subject expressed in the context of tax law.
IRS Finding regarding Frivolous filing Sovereign Citizen

HOLDING...Snip
"1. The Fourteenth Amendment of the United States Constitution establishes simultaneous state and federal citizenship. Therefore, an individual cannot reject citizenship in the United States in favor of state citizenship, or otherwise claim not to be a citizen of the United States for the purpose of avoiding federal tax liability. Furthermore, income earned within a state of the United States by a United States citizen or resident is taxable under federal tax laws. Accordingly, Taxpayer A and Taxpayer B are subject to federal income tax liability because they are citizens of the United States and citizens of the state in which they reside.2. The term “person” as used by the Internal Revenue Code includes natural persons and individuals. Moreover, a taxpayer need not request, obtain, or exercise a privilege from an agency of the government to be a "person" within the meaning of the Internal Revenue Code. Therefore, Taxpayer C and Taxpayer D are subject to federal income tax liability.
CIVIL AND CRIMINAL PENALTIES The Service will challenge the claims of individuals who improperly attempt to avoid or evade their federal tax liability. In addition to liability for the tax due plus statutory interest, taxpayers who fail to file valid returns or pay tax based on arguments that they are not citizens or persons as contemplated by the Internal Revenue Code and, thus, are not subject to federal tax face substantial civil and criminal penalties. Potentially applicable civil penalties include: (1) the section 6662 accuracy-related penalties, which are generally equal to 20 percent of the amount of tax the taxpayer should have paid; (2) the section 6663 penalty for civil fraud, which is equal to 75 percent of the amount of tax the taxpayer should have paid; (3) the section 6702(a) penalty of $5,000 for a “frivolous tax return”; (4) the section 6702(b) penalty of $5,000 for submitting a “specified frivolous submission”; (5) the section 6651 additions to tax for failure to file a return, failure to pay the tax owed, and fraudulent failure to file a return; (6) the section 6673 penalty of up to $25,000 if the taxpayer makes frivolous arguments in the United States Tax Court; and (7) the section 6682 penalty of $500 for providing false information with respect to withholding.
Taxpayers relying on these frivolous positions also may face criminal prosecution under: (1) section 7201 for attempting to evade or defeat tax, the penalty for which is a significant fine and imprisonment for up to 5 years; (2) section 7203 for willful failure to file a return, the penalty for which is a significant fine and imprisonment for up to 1 year; (3) section 7206 for making false statements on a return, statement, or other document, the penalty for which is a significant fine and imprisonment for up to 3 years or (4) other provisions of federal law."
