Take on Airline passengers getting weighed

Airline passengers will have to get weighed before boarding a plane which is something we've been pushing for on this blog for a decade. Airlines are trying to figure our how much total passenger weight they are carrying so that they can add more cargo. This is fine for their corporate profits but does not address my concern which is when I am sitting, I'd like to sit next to somebody without them putting their gut into my lap.

My issue is that if they are encroaching into my space, I should be the compensated, not delta.
