“...spread the cost of these idiot regs over the cost of many buildings.”

Can you explain to me how you spread variable costs via economies of scale?

The best example would be a home owner building their home verses a developer building 100 homes.
The 100 homes are essentially the same, energy calcs, would only have to be done once for the 100 so each home would have that cost at 1/100, where as the signle home bears the total cost. Hopefully, I explained it a little better
