People saying stupid shit sure make it hard for freedom to truly exist. Let alone all these threats to security. Technically, absolute freedom is no better than chaos. So we all need some sense of Order to survive and thrive. Society, structure. America for example isn't the "land of the free" in an actual sense but it is more free than other countries. There are always people that make it necessary. Like, living without a government. I don't believe that is possible and it seems incomprehensible as to how it would be. Absolute freedom would ve very dangerous.
Can we have inner freedom? Depends. We are always influenced by everything around us. But if you discount that as an issue, perhaps an inner freedom is being yourself. In which case, we also rarely express this in it's full extent. Do to many societal expectations to fit ways of being.
We grow up, go to school, work our lives away until we are old and retired and die off, passing on, as per usual children to do this same thing. Again, and again. A never ending process which in itself is hardly freedom in the literal sense. We must all fit into the system to keep the gears going. Often, it isn't even a job we like but have to do to survive. This is survival. Surviving isn't free.
I think an absolute freedom would be foolishness. Anarchy in it's truest sense would be severely dysfunctional and crippling. We always need some sort of system.
The limitations of reality make reality.
Freedom means being able to make choices.
When you make a choice, between two or more possibilities, those things cease to be possiblities and become thing you have chosen becomes reality, the others, cease to be a fantasy. They are not
even a fantasy anymore.
Reality, btw, can be beautiful or horrible, depending on our choices.
Now, you talk about how we need a system. I kind of agree, but not any system. As humans, we build systems. In a "state of nature" a-la J.J. Rousseau, we have a limited amount of choices to make. And for our "cave man" ancestors, nature was their greatest enemy. Illness, predators, and their living conditions made life very difficult. So they had less choices to make, in this state. So humans invent civilization, and while this brings alot of improvements, it also brings tyranny, in some cases.
The point I'm trying to make is that while a system and civilization is good, I think, it also allows for some abuses, like tyranny and dictatorship, which I wouldn't consider "civilized", but it comes with the territory of governments and rulership. So I think we need government, we need society, and we need civilization, but if we live under a tyrant, a dictator, it takes away our capacity to make choices in our lives. Thats why I want to support politicians who support our freedoms(if there are any), our freedoms to make choices in our lives, not assholes who want to take them away.
Yeah, yeah, I know,I know...
I think too much.
