Well people don't have to purchase Ferraris, there are cheaper alternatives like purchasing a used car. So, false equivalence.
There's no equivalent to the internet, as far as I understand. You can get a level of service, and if you want a faster or more stable connection you can pay more.
The fear around losing Net Neutrality is the fear of losing unfettered access to the internet at large. The fear that an ISP isn't going to offer a "general internet" plan but instead charge the consumer extra for access to various services like music streaming, video streaming, VOIP, or other media. Or even conflict of interest. BigCo may offer their own video streaming, or charge the consumer an extra $20 for the Netflix/Hulu package, an extra $10 for Youtube and Vimeo, and access to any other sites, or sites not paid for, are throttled.
It gives the ISPs more power over what we can or cannot see, what sites we can or cannot go to. When so much of modern day society is on the internet, this is frankly worrying.
