If you have a point, and I don't mean this in a prejorative way, what is it?

Of course it makes sense to put business rules in the middle tier. I don't think anyone has argumed otherwise.

The question is rather whether you put ALL of the business rules into the middle tier.

And quite frankly were the choice as you have put it forward I'd put to your customer the following question:

"Is it more important to you to the $X by putting everything into a vanilla middle-tier or having security, scalability, and performance?"

I have been hired by several 'name' software companies after they tried it your way. And each and every one has reversed that decision after their customers refused to by their damaged goods.
