Right they’re not violated, but my point is that they’re almost never the impassible barrier that people make them out to be.
It’s not that the rough approximations are wrong it’s that people focus too much on one or two ways of doing things (using atmospheric air as a reaction mass to fit my first example) until someone creative and knowledgeable enough finds a new way to do them (rockets then.)
It doesn't seem startling or interesting that people continually find ways around rules that are not rules.
