Anyone could choose to pay to fly in big roomy seats. It’s called business and first class. People do not want to do that, which is why people not only keep buying tickets in economy, but buy tickets on budget airlines that are even more cramped, less comfortable, and have less amenities. You are renting space on the plane for the duration of your trip. If you want more space, you are free to purchase it. If you deliberately chose to purchase a seat you know does not fit your needs, then attempt to steal space from the person next to you, then you are the bad guy. Not the airline. If you think you deserve to be gifted free additional space you did not pay for, then you are the bad guy.
