Ripping every single plug socket and outlet out in 80% of the living spaces in the EU is neither cheap nor popular, so "industry asking for it" will not be enough. Your comparison is a bad one.
Most of Europe already has a standard 230V plug (https://en.wikipedia.org/wiki/Schuko). It would probably be easier to get a unified 230V power plug than to change the USB-C port again after a decade.
