Noob. You just want things easier. Minecraft is too easy these days anyways.
Okay, your argument is horrible, but just to entertain you, here's some food for thought.
You're right. This does make things easier. In Single Player.
In Multiplayer, a lot of survival servers are PvP-friendly. If horses are abundant from the start, the range at which your base would have to be in order to not be detected by incoming PvP/Griefers increases exponentially by how abundant they are. This would make things a hellish fustercluck (if you'll excuse my fowl language) rather than easier.
