IF this practice was not done then wouldn't resulting generations have fewer defects and therefore have a greater percentage of saleable fish and therefore result in more money in the koi breeders' pockets...

I wonder where are the proofs showing that *breedeers* use defective Oyagoi ON PURPOSE? Who does consider appropiate using flawed Koi as Oyagoi? Excuse me, but all that seems quite unbelievable. I will acknowledge if you can provide more information supporting your statements.
I believe that serious japanese breeders are honorable and do an excellent work.
Getting a lot of variation among sibling tosai from the same spawn doesn't means (at least to me) that the parents are defective. I think it happens because most varieties are still "too young" and not well fixed yet.
Be sure that tens of thousands siblings of each Grand Champion were culled just because they were not valuable. That is a fact.
True selection involves continued work with a lineage along several generations. It implies keeping and breeding the very best of each generation in order to fix the desirable traits, while seeking to minimize inbreeding at the same time.
A breeder might obtain and try several set of parents to start with, each fish being awesome. If one set of parents work well in the sense that they produce a good proportion of high quality fry, and since Koi can last decades, one can imagine that the breeder would keep on breeding with the same set of parents for years. Hence, that's just a first step to build a true lineage.
Peter Wadington wrotte in an article that the production of the best breeder of Purachina in Japan has relied for years in a given set of Oyagoi. Would the female fail and the breeder coul be in trouble to find a new Oyagoi being able to produce the same quality offspring.
Apparently some breeds of dogs are not well fixed yet. A friend of mine is international judge, and told me that good Rottweilers are particularly tricky to breed. The sons of international champions can give birth to "mutts".
Back to Koi, you have to consider that in case a breeder had excellent parents producing 100% of their progeny with the same excellent quality, two things might happen:
1) culling would be also mandatory. After all, who's got enough space available to raise millions of fry until they reach a saleable size?
2) I guess that a huge increase in supply of high quality tosai would lead to a decrease of prices, that's pure law of supply and demand.
Koi are said to be living jewels, and true jewels are so valuable mostly because they are scarce and difficult to obtain. I guess this also apply to Koi.
