Great post, i think you just missed one increasingly important aspect:

You dont have a monthly cap on how much of your surroundings you can take in; many people have caps placed on how much data they can download.

There is an actual measurable cost to advertisements over a metered data plan. It literally costs you money to even see an ad.

If it was 50 cents per MB, are you still going to enjoy that delightful little advertisement that just cost you 3 bucks to see? (obviously a hyperbolic price, but its the concept that matters here)

If you are 1MB away from your data limit and you go to some small website that loads 2MB worth of ads - are you going to be okay with paying an overage charge for viewing that advertisement?

I take your point - I have no hard and fast cap on this adsl broadband over copper connection. Reminds me in a way of the annoyance with faxed adverts we used to have decades ago - that might be a useful analogy if you are dealing with PHBs.
