If you were blind at birth, you would be totally OK with it. If you drive only being concerned with what is in front of you, I doubt there would be laws requiring rear view mirrors. I have driven many trucks with TCs over the years, towing and not towing. I was OK with that. With limited visibility to the rear, I hopped when I changed lanes I did not cause an accident. Who cares if an emergangy vehicle wanted to pass.
I installed a Walmart wireless camera on my wifes car. I have nothing to nice to say about the camera or its use. It is unbelieveable how many wires were required to install a wireless camera. The camera would go nuts for no obvious reason, and all you would see was snow. I then did some research on wireless Cameras, and discovered what I experienced was very common with wireless cameras, especially the cheap ones.
I finally ordered a real camera. It took longer to read the instructions than to do the install. Three screws to fasten the camera, one wire from the camera to the monitor, two screws to mount the monitor, and plug the power into the cig lighter. It was not cheap, about $400. It does include night vision, sound, and wide angle.
I use my camera as much when I am not towing as when I tow, day or night. I still have one small blind spot on the passenger side of the TC, but I can see to change lanes. It is especially great in tight spots when backing up. It exceeded my expectations. If it were to quit working, I would replace it. As I said earlier, if you were born blind, you would not know what a great thing it was to have vision.

EDIT: This is where I bought camera, several years ago. They are very easy to talk to, especially in identifying what would work best for you.
