The only argument here is "it might not be necessary, so it's not worth the costs." Can anyone think of any actual costs? Unfortunately there is no substance in the "THE COST OF REGULATION" section.
People with more of a network background will please chip in whether this is easy?
Also, more speculatory:
Free-you're-the-product services are dominant in large swaths of the internet. Free-and-you-don't-pay-for-the-bits-you're-still-the-product could be up-and-coming, but Net Neutrality regulation would kill it off as obviously evil. Who knows, it could be an essential stepping stone towards people being paid for all the data they feed tech companies. Maybe Net Neutrality will lock in free-you're-the-product indefinitely.
