Is it permissible to prevent neighbors from parking their cars in front of the house, and does the sanctity of the home include the street opposite to it?

If there is no law giving priority to the homeowner in adjacent parking spaces, then everyone is equal in this right. The neighbor has a great right, so they should not be prevented from parking in front of the house, especially if the parking spaces are public. The neighbor should also avoid harming their neighbors by parking in front of their homes.
