ELI5 Why do horse hoofs need so much care, and why do they need horseshoes?

Wild horses seem to get by just fine without people caring for them. How does all this care make their hoofs different/better than if they stayed natural?

Wild horses are constantly wearing down their hooves on rough plains, rocks, gravel. Just like our own finger nails, if you let them get too long they split, can lead to infection etc. Trained horses on the other hand have relatively soft stables and paddocks so their hooves don't wear the same way and periodically need to be trimmed. Working horses on the other hand (like mounted police and draft/carriage horses) spend a good chunk of their day on pavement which would wear down their hooves too fast, hence the shoes.
