I read what you write. I do not have any disagreement with anything you have written.
What horse ownership is all about is: committment by the owner to the horse's wellbeing 24/7 x 52 a year.
And whilst there are "gaps" so to speak when -I- can't be there, I'm lucky to have a situation where another person on the property -can- look after my horses for me (ie feed them hay, check them over, make sure they're okay). It's a far cry better than others over here.
