It's not a Tax
This is not a “tax”, you have no obligation to pay it, watching live broadcast television is not mandatory. I do not have a TV, and the whole concept of wasting hours of time watching whatever shite happens to be getting beamed into my house every evening seems very strange.
Clearly the future is not live broadcast television, and that’s been the case for many years. As such, the TV License is an archaic and not fit for purpose piece of legislation and requires overhauled to reflect the modern consumption model. Even at that, I don’t have Virgin Media or Sky sending thugs to my house to try and strong arm me into buying their services. They take the very simple measure of encrypting their services. The BBC on the other hand beams its entire content across the airwaves and internet then makes the arrogant assumption that people not paying for their services are criminals.
If you intend to be legally license free, simply ignore all correspondence from Capita. Close the door on them if they call. Do not give them your name or any details. DO NOT allow them into your home or give them an opportunity to find “evidence”. They have no legal powers and you have no obligation to engage with them at any level. Successful prosecutions are nearly always due gullible people being tricked by the thug on the doorstep into self-incriminating.
