If all of the above were true it would be great for new companies and great for consumers with the downside of being unreasonably expensive to the middlemen (car dealerships, grocery stores, etc.). I would say the same thing doesn't apply to internet companies. It's not unreasonably expensive for them to carry all websites and in fact they are making great profits. I don't think the internet companies gaining more profit (by not being neutral) is worth the consumer and new company benefits lost.

The other major issue is competition. All the above examples have a lot of competition, but internet companies are a lot of times monopolies and duopolies. The consumer has no choice but to use them.
