Shouldn't fat airline passengers pay for two seats?

This internet post caught my eye. I have been in similar, though not as extreme, situations. I am 6’5’’ and 200 lbs. I take up room horizontally, but not transverse. My flying experience is already compromised for leg room. It would be really annoying to have to give it up to a wide body simply because nobody wants to admit that some people take up the space of two. Solution- Charge for and reserve two seats for the folks who can’t fit into one. What is wrong with that?
