People often wonder why asgardians still ride horses if they have all these technological advancements and flying ships etc etc, and my answer is that horses are a rich people hobby. Owning a horse is expensive. Vets bills are expensive. Maintaining the land a horse needs to comfortably live is expensive and time consuming. Realistically, the only asgardians who actually own horses in their modern age are farmers who cant afford fancy machinery, and rich people who want a hobby and can afford to outsource all the labor that comes with owning a horse.
I think it's the asgardian version of romanticising a more rural idyllic past, whilst pricing the hobby out of reach for the vast majority of people to maintain a degree of seperatation from the realities of that rural past. Theres a reason we only see asgardian royalty riding horses in the movies
