While you may be less subject to corporate power structures the way you are operating now, you are still subject to all kinds of other power structures. As the GP has submitted, try working against the power structure of the country you are living in and you most likely will suffer greatly. The same even happens on lower levels (state, municipality, family?).
And even regarding corporate power structures you are only avoiding a certain kind of their possible influences. For example, if a corporation buys up all water supply in your living area you can feel that influence, even if you are not working for them.
Agreed. You don't even have to work against them, if your ideas are seen as a threat, you will suffer. The worst part is that most of the people who will make your life difficult don't even understand what they're doing. They're just doing their job.
Your ideas could be potentially highly beneficial to society, they might benefit everyone including those in power but if it's against their beliefs, you will be punished from all sides.
