It's all about what your final goal is. Do you want to have a horse for your own enjoyment and go by the "if it aint broke, don't fix it" regime.. or do you want a companion that you spend time with and will do everything humanely possible to ensure that they're consistently happy?
I'm definitely the latter individual. I board, and I would go without any amenties like heated wash stalls or groom or whatever as long as my horse got his chiropractic appointments, his supplements, his bi annual vet shots, hoof care, and his check ups when something isn't right.
That doesn't make me a better owner or a more correct owner than someone else. It's just how I choose to care for my horse, and how I encourage others to as well.
That being said, I am obsessed with riding to be the least pain to my horse. I know I have MANY flaws, and rather him be nice and happy with me taking lessons on a regular basis, than so-so with me kind of wrangling myself into riding him how I think I should.
Ignorance is one thing, stubborness is another. As is everyone's perception of what a good owner consists of. I know MANY owners that don't have arenas or even tack rooms, never has their horse seen a chiropractor but their horses are fine. I know my own horse would not be nearly as happy like that because he has a past with lots of baggage so I do my best to make him as comfortable and happy as possible :) And that for him.. means all the "extras"
