If you had a large choice of ISPs, then Net Neutrality wouldn't be required. It would come by default as the client could move from a restrictive ISP to a less restrictive one.

Since there is virtually no competition in large parts of the world, it is very important to force the single monopoly to behave in the interest of the consumer with laws.

The regulations the author is talking about are not the same regulations that enforce net neutrality. Net neutrality has nothing to do with sharing telephone poles.
