I believe that when you apply a free market to a good, you will get more of that good at a cheaper price. Can this work for ISPs I believe so. Would it work perfectly? No, the free market works in a zig-zag like exploration process. But the real question is, would the consumer be better off under a free market system, or a centrally planned system? I always vote for a free market system 1. Because I believe it’s more moral to allow people to freely associate with one another 2. Because I believe it is better at solving problems over the long run.
The second part of your question is asking about other regulations on ISPs. This does complicate things. When I speak of the libertarian position on ISP free markets, really, it’s a theoretical claim about fully free markets. It doesn’t make any free market or libertarian sense to remove one regulation but to maintain many other market distorting regulations like territory restrictions. In that case, I honestly don’t delve into intricate policy recommendations. My focus is to inspire people about the large scale concepts of freedom, free will, and free markets.
Thanks for the measured, educated question.
