Not sure where you are getting your information from, but nowhere is it stated that our liner rated for only 60-80 days of use. 150-200 days is our standard life expectancy. Obviously, that can change with how well or how poorly you take care of your gear, or how hard you are on your gear.
The Surefoot business model is one that is becoming less and less popular- more and more shops are including the fitting costs (labor charges) in the price of their boots in order to stay competitive with internet sales. That normally means when you buy a ski boot from a shop, they perform stretches, grinds, liner molding, shell molding, free of charge. Additional products, such as foam liners or footbeds, are not included but you would usually get a discounted price on them for buying your boot from that shop in the first place. So, more often than not, you don't need to spend an arm and a leg to get a great fitting pair of boots. You can get an amazing fitting boot for $500 bucks, custom footbeds for $125-175 and have a boot that lasts easily 150-200 days of skiing.
Of course there are more expensive, higher performing liners that are available aftermarket (most brands, including Atomic, make them) that will result in a longer lifespan, but they will not be cheap. So, it's never going to be the case that these two products will ever be priced the same as you suggest in letter c.
I definitely agree with you that people should be skiing with a good, supportive footbed that works with their foot shape.
