Perhaps they aren't saying that the internet is like a physical location, but rather that like physical locations the internet should be made accessible for everyone to the greatest extent possible. That's a much less ridiculous way of framing the argument. I absolutely think that if you operate a business online there should be some minimum of accessibility you need to achieve, in exactly the same way we force physical locations to install wheelchair ramps.
