-SCH repair cost range is $3k-$25k [avg ~$10k?]

THEN the avg SCH repair cost per M owner is about $100 ($10k x 1% = $100)...

Like I said, I'm happy to take that risk over spending $3k on a solution.

***this is just my opinion based on the speculative numbers. Also, I only plan to do a moderate BM3 Tune on 93oct. IF I was going much heavier mods (I.e. new snails, e85, etc.) then that would probably sway me more into thinking about a solution. Again, just my opinions here...
Why would a SCH repair be $3k (a ridiculous number with no basis) and the average $10k.

That sounds like wild speculation to make your case.

Furthermore, a time line has not been reasearched to determine how long after manufacture the SCH occur - an event that will increase over time with more miles on the cars.

I say that with 110% confidence because if all F8x were immediately parked, the total number of SCH immediately quit increasing. As more miles are put on, the SCH failures will increase.
