The foundational principle (which is really just a metaphysical reality) of voluntaryism, is individual self-ownership. This means that I have the highest, most direct, nature-conferred executive authority over, and right to exercise, use, and own, my life and body, and so does every other individual with respect to their individual self.

Choosing to have a smartphone, or a computer, or any other tool is not in violation of the principle of individual self-ownership. These are inanimate objects which can be used for good or ill. One can freely choose to acquire these tools, or not. Nobody is directly forced into anything, as with actual slavery.

By your own standards, the fact that you use a blockchain-based social media website could be twisted and skewed to the interpretation that you don’t mind each of your transactions in Steem and on social media being tracked.

You’re an anarchist. Great. That’s excellent. Telling others which technology they can or cannot use is pretty silly, though, in my view.
