A YouTuber makes this claim - do you agree?

So, I was on YouTube and I watched this video and this girl made this claim. She said that no one absolutely no one needs 5+ horses. That’s outrageous etc. You don’t have enough time to spend time with them all and they need x y and z.

What do you guys think? Is 5 too many? I wanna hear your hot takes!! I think there are so many factors to consider to even make such a claim, but that’s just me. Do you board? Well then yeah 5 would be crazy because the boarding fee would be very expensive. But if you have 50 acres then having a small herd like that might be nice.
