Moving the cone to take the spot that’s reserved isn’t clever. It’s just deciding your time counts more.

Whoever put the cone there had a reason, and the reason belonged to somebody: a delivery, an accessible space, a person who will arrive to find it taken. Moving it is not a clever reading of a loophole, because there is no loophole, only plastic and an assumption that people respect what it marks. What the move announces is that your schedule outranks theirs.

When you catch yourself building a case for why a rule does not apply to you right now, the strength of the case is the warning. Park further away and walk. The three minutes were never worth being that person.
