What do you value? You can also make this argument to advocate ignoring web accessibility because its not a cost benefit tradeoff that is worth a single entity’s bottom line for the sake of the small percentage of people that are disabled. Private actors in the capitalist economy regularly make very shortsighted decisions. It’s up to us to establish the boundaries in which those decisions get made, and to some extent, our laws are a reflection of our values. What kind of world do you want your possibly disabled children to grow up in? (Edit: and what kind of sentiment do you want to be established in society and the industry when you are 50+ years old and looking for a job?)
