Boots are like horseshoes you can take on and off any time you want.
I think that is a great option to have.
I don't know why mentioning that promotes such hostility.
For some people and some horses, barefoot works great. If it doesn't work for you fine. But what's wrong in mentioning it as an option?
The beauty of the boots it that you CAN have hoof protection when you need it. And they can be barefoot the rest of the time. It actually gives you a lot of versatility.
It even gives you an option if you, heaven forbid, loose a shoe, and worry that the horse will get sore without it.
