I can buy apples at a somewhat objective price by comparing the price provided by other sellers in nearby stores. Also the price will be mostly affected by supply vs demand.

OTOH, softwares prices can be affected by too many parameters.

Then again, IT industry is a child when compared to say, mechanical or Civil industries.

Your first method just overprices/wrong-prices the whole market. I'd argue that supply-demand doesn't give fair pricing (which presumably is what's meant [in part] by objective), if you can make something very cheaply does that mean you objectively deserve to be very rich simply because you've got a corner on that market?
