If my property bordered an alley where literally every surface had been covered in murals for decades, and I discovered that the organized non-profit coordinating murals in that alley, who had a long-standing relationship with all of the property owners, had set an artist up to paint a new mural there, then I would be happy, yes.

Or if I were unhappy, I would talk to the artist and/or the mural organization about it, ideally before they had put too much time into the project.

I certainly wouldn't wait more than a decade after the murals were finished and then on a whim decide to paint over them, erasing months (?) of artists' efforts in an afternoon.

I don't know why you are putting "mural" in scare quotes. The works in question are clearly murals, not just graffiti tags or something.
