He wasn't interfering with the building owners. You're making up a justification to screw this guy over. That's really sad.
(You forgot to use logic or explain a point of view and instead just made a random moral judgement and expressed the emotion it made you feel, so I had to make some assumptions about your intentions and depth of thought)
And your first sentence makes no sense. That's not how people usually work. They get possessive and risk-averse and ban things that are unusual. That "if-then" is a total joke, and without it your criticism of my argument falls apart.
