I can't speak for anyone else, but I guess we say jumping on furniture is disrespectful because the furniture is important to us. We take care of things that are important to other people. Whether that is a cheap couch or a fragile ornament, if someone says they don't want it played with in a way that will damage it, then we have to respect that. And by 'we' I mean our family. As they get older there has been and will be more opportunities to teach respect, but furniture is a start :)
