A free definition of freedom of speech

Article 19 of the Universal Declaration of Human Rights, adopted in 1948, states that:

"Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers."

Although this definition appears absolute, governmental and other compulsory organizations have felt morally obliged or entitled with the mandate to restrict free speech with varying limitations. Common limitations on speech relate to libel, slander, obscenity, pornography, sedition, incitement, fighting words, classified information, copyright violation, trade secrets, non-disclosure agreements, right to privacy, right to be forgotten, political correctness, public security, public order, public nuisance, campaign finance reform, perjury, oppression, religious offense or incitement to ethnic or racial hatred.
There’s not such a thing as the right of freedom of speech that needs to be defined or restricted. Instead freedom of speech is a condition that stems only from a human being's right to property. The attempt to coercively enforce morality have found its way by simply aggressing those property rights.
To achieve a condition of unconditional free speech we must simply find, fund, or found a decentralized system that can’t be aggressed and can’t aggress property rights of its actors.
