Beeping and beeping and beeping until his soul blossomed

A question: In a certain locality, someone put a barrier on the parking lot so that only he can park there. It may really be more related to him because it is closer to his house, but of course it is not a taboo or anything.
The device beeped and beeped and probably gave out juice to all the neighbors. Someone probably uprooted it from the parking lot and threw it in the trash.
The person who put the device in screams and screams again and again (he learned from his broken device) that he was robbed because the device costs 500 NIS, according to him.
1. Is it permissible to block parking that is not necessarily related to a particular homeowner, but rather based on a reasonable assumption that at least one space somewhere on the street belongs to him?
2. Is it permissible to throw a device that is constantly disturbing and beeping in the trash? (For example, a car with an alarm) of course within a reasonable time for the homeowner to take care of it and silence it and be negligent?
3. Even if in general it is forbidden to throw away the harmful device, if it is in a place where it is known that people live there who think more with their stomachs and less with their heads (bibists) and much of the walking there is done in a way governed by their stomachs and not by their minds, and it is likely that they will behave in the same way with a device that is disturbing, can it be said that it was done because of a good conscience and this is the custom of the state of that place, and therefore it is a waste and it was permissible to throw it in the trash?
