I suspect that Intel produces such processors to meet the requirements of institutional customers engaged in areas like national security and other matters related to nation states, i.e. customers who need laptops and are sophisticated enough to write procurement requirements down to the CPU level when soliciting bids.
It's basically the same logic that produces chips with vPRO; there are a set of important customers who want to be able to manage CPU's remotely. Because that group buys many more chips, the default is to include vPRO. The volume that those customers buy produces the economies of scale that let vPRO chips dominate the consumer market.
