Your post is simply illogical, you made little connection between cars and internet.
Fact: Most affluent people in the world have high speed internet, most affluent people in the world have cars, these affluent people are our target market.
So let me see if I am getting what you said right; You think that because everyone already has high-speed internet it should not count? I guess it is beside the point that most people also have cars.
Based on "It shoudn't be counted as a cost. However, gas should be, because if you get home and someone then wants to watch a movie, you have to go back to the store just for the movie" - that is a BIG if, what about when they don't? And they go to the store and get a movie, then it would no longer be an expense correct? Because the internet isn't an expense to you since everyone already has it.
So because they made a judgment error it counts as an expense? What if someone comes home and wants to watch a movie on ReelTime, they have to turn on their computer and connect to the internet to do so. Is this not comparable to the analogy you just made? How can you just discount the cost of gas with no real allocation? Gas costs money and so does the internet, they are both expenses. That is the bottom line, anything else is simply choosing to be ignorant of the facts.
It just seems like people are making the generalization that because everyone already has it, it is not an expense. Well, most people already have cars, they even usually already have gas in the car!
There are two analogies I see as viable:
Everyone drives cars and everyone has the internet, so therefore neither is an expense
Everyone spends money on gas and everyone spends money on the internet, so therefore both are an expense.
Not a valid analogy:
Everyone drives cars and everyone has the internet, but IF they have to go to exclusively go to the video store to rent a movie then that specific instance should count as an expense.
You see in the first two both sides are accounted for, in your specific example they are not.
And where do people who say internet is not an expense account for paid WiFi fees? You say internet is completely mobile, but as soon as I leave the WiFi signal of my house, I have to pay for it. Internet Cafes, hotels, airports, all these places, they charge for use, and they charge A LOT. Where do these costs come in aside from the home high-speed internet bill?
