Apparently it seems you have a great idea about production costs 
Make a proposal to Jens then so we can have tonz of hardware on our disposal and never have to worry about end-of-line products!
I am pretty sure Jens knows of this, considering he is actually in the business of making things and I am in the "boo hoo, I didn't have the 160 bucks when they were still at vesalia and amigakit so I'm boned" camp. I would just prefer he got something of 160 bucks as opposed to none of the 300-500 that Denebs and Indivision 4000/1200s go for on fleabay, amibay, and other places.
Not everyone has disposable income when these things are available. A large part of keeping the original amigas alive and kicking would be easy availability of (at this point) required hardware that doesn't have to be bought at huge markup from private hands.
