But you see Nick, Coopers have a Co-Gen plant (basically a Concord jet engine spinning a generator), the wast product is heat, enough for all the brewery, free heat means boiling doesnt cost money.
Ok I get that you dont like kits and Im an AG brewer to, but youre making wild sweeping generalisations without a factual basis to work from. If you want a contention to stand prove your case. I thought kits were made from Iso, I put that question to Coopers and I was wrong, if you search you will find my apology for spreading disinformation for so many years.
There are lots of reasons to use Iso, the main one is consistency big brewers want every batch to be the same Iso allows very precise control. There is no variation, the product is standardised as is the (generally boring) beer made from it.

Sorry
Iso-Hops are extracted and purified Alpha Acid (the main bittering part of hops), this is then chemically Isomerised, converting about 30% of the Alpha Acid into Iso Alpha Acid, the balance being un-convert Alpha Acid and other hop oils (depending on the process used).
Can be added post fermentation in very exact doses to provide precise bitterness control, generally not thought of as a nice tasting bitterness, regarded as harsh and two-dimensional
