The airlines are dealing with the size people are by, in your example, preventing those oversized for their chosen seat from negatively impacting others.

They do provide bigger seats at a higher price point though. You have chosen not to make use of them and then blame the airline. If you are big enough that sitting next to someone your own size causes you discomfort then you would be encroaching the space of someone smaller sitting next to you. That wouldn't be fair to them.
