Freedom is subjective. There is internal freedom; one that can only be changed from within, and external freedom; which can be effected by social, economical and political issues.
Although internal freedom may seem easier to achieve, it is in actuality very complicated to argue. The Idea of free will: believed in religions such as Christianity, Judaism and Islam explain that we have been give free will by God to do as we please. Yet conditions such as Tourette's and other mental illnesses go against this idea. Other possible beliefs of multiverses and mapped out lives for each person; in order to for fill a purpose, all question the ability to have internal freedom. Theravada Buddhism teaches that in order to be free, which in this case is 'Nirvana', you must not hold tightly or desire anything, instead you must stay away from evil and keep your mind pure. Many, therefore believe that in order to achieve freedom, they must lead a pure and simple lives.
At this point in time external freedom is unlikely to ever happen. If we automatically allow ourselves to have internal freedom then external freedom can never be achieved. If humans are allowed internal freedom this means they can do as they please, this causes social issues such as racism, sexism, homophobia ect. Political issues caused by politicians who run only to achieve power and wealth and lastly economical issues cause by the existence money prevent external freedom from ever being achieved. So therefore although I understand the idea freedom is subjective for example some may see freedom in nature. At this moment in time both external and internal freedom can not be achieved so therefore freedom is impossible, to be free is to be dead.
