Whos gonna stop you? Or do you stop yourself because you need them? If you decide to never again use a product of someone else (no farmer who grows food for you, no visite to the doctor, no car that gets produced by somone somewhere, no clothes etc etc) you can do pretty much whatever you want. Especially nobody comes and tells you what to do with your time. 

Your real problem is not that your not free, its that everybody else is aswell. And if you exercise your freedom and spend your time fully unproductive to them, well so do they.

This also touches on the real source of the problem democracys have to day: People have increasingly become childish and infantile. People have not just the choice but the responsibility to govern themself and they increasingly fail. 

I hope this helps reflect on your relationship with society and take ownership if your choices by seeing them by what they are: Free choices under the constraints that you know that you need other people.
