The industry does use frozen semen. Most often it is used in proven horses so that a particular stallion will be having offspring years after his death. There are some that will collect a prospective colt before gelding but it is not generally cost effective. If the horse does not perform well, the effort and cost is wasted. Again, it benefits the money folks which in turn creates a monopoly.
To be clear, I don’t fear cloning or even frozen semen long term. Using cloning and frozen semen(for a longer duration breeding program) stalls the advancement of the breed. You don’t get improved traits if you narrow the gene pool by breeding to clones or old stallions.
I do fear the short term damage to the industry as new people interested in an equine sport will be shut out and unable to compete when/if there is a surge of horses, all closely related, at the top of the performance curve. There is no room for new people to get involved. This is already an issue in the racing industry. As top tier owners/breeders corner the market on genetically superior horses, they only have themselves to race against.
But to your point, yes frozen semen does offer the ability to deal with gelding. That just goes to my point that those wanting clones are trying to fix a decision they made and lost on.
