300 Trojans died at Thermopylae for freedom. You could say it was for the "illusion of" freedom. But that tells us nothing about them and a lot about you. Likewise, over 100,000 Britons died for the right to have taxation based on the consent of the Commons. What exactly is the point of saying they died for "the illusion of" freedom. Do you seriously imagine the concept of freedom in 350 years will be the same as it is today? Are you arguing for the "illusion of" freedom yourself?
We're not talking about freedom. We're talking about taxation, democracy, and consent. Sparta (not Troy, btw) was anything but a democracy. I suspect the non-standard definition you're using is in deed "democratic," given that you keep referring to representatives and monarchies as your examples of "democratic consent." Let me correct that:
de·moc·ra·cy
/diˈmäkrəsē/
Noun
A system of government by the whole population or all the eligible members of a state
If you're looking for a Classical example, Athens would be your best bet.
But even then, Democracy is based on a logical fallacy: The idea that because an idea is popular, it is the best.
Again, that tells us nothing about history and a lot about you. You think that you can apply your 21st century ideas to the people who lived 100s of years ago and that makes you superior.
