One could build dedicated parking structures. Those use up less space that we can use for much better stuff, make it so that you don't have cars circling blocks trying to find parking. If a business decides that they need parking, nobody stops them from building it themselves. No reason to dictate this or have the public give up collectively owned land for this.
