Well good for you guys in 1st world countries if physical media dies, bad for us 3rd world countries with f@cked up internet infrastructure and services.

Can't these games just fit a microSD or something instead of a disc base media?

50gb of game would need a 64gb microSD, which are ungodly expensive. 

But developers rarely use 50GB space anyway, surely there is other cheap alternative to Blu Ray that won't let quality suffer?
