For the simple reason, freedom cannot exist without its paradox. The paradox that must consist of rules to protect the trust and integrity of collective freedom from being eroded by a vile-maxim of personal freedom.
Remember that no matter what the market construct of your preference, individual participants will always attempt to abuse the workings of such a marketplace with their needs put above everyone else’s. Hence rules are part and partial to any marketplace in which the collective interest must be protected and paired with individual interests, and to ensure such collective trust and interest continues to invite new members to participate. Without the protection of collective interest as the paradox, any marketplace will very quickly erode.
Not all enforcement of the paradox needs to be automatically handed over to a government, but the private sector generally is an inferior judge of collective interests, as it is usually not rewarded for doing so by the short-term interest of “the street.” Hence, the protection of the collective trust is generally bestowed upon government, post-mortem rather than preemptively, when the fallout of a lack of collective freedom has already occurred.
The good news is that technology companies have a tremendous opportunity to self-regulate such collective interest as part of the encompassing systems they build and thus have the chance to prove to governments they understand what perpetuates a plurality of freedom that encircles the world. Very few have done so and therefore will meet the sickle of societal discontent, controversy, and abandonment.
