I am sure that others may have a different view......... But fixing them is not always economic.

Since the OP stated "Ignoring cost/benefit entirely, assuming we're talking about lug set-back, can this issue be fixed? If so, who would do it and any ballpark as to cost?" I attempted to answer accordingly.
Often, there are intangible benefits that shape our decisions, not just a strict cost/benefit analysis. There's a benefit to some in hunting with a certain rifle, or a type of rifle, that can't be overcome by cost savings alone.
But, on the whole, you are correct, it is probably less expensive to find a cheap rifle that to fix said problem.
