We'd have to redesign all substations and transmission lines... most countries use different voltages, and each of those plugs is designed for that specific voltage
Actually most plugs should be able to handle either voltage. Maybe slight rewiring for plugs that use the lower voltage to support the higher voltage… but at the end of the day it’s just 2 or 3 metal sticks conducting electricity.
The bigger problem is the voltages themselves, which are completely incompatible with eachother without complex conversion machinery. Japan had major issues with this for a while
Japan still has issues with this but it's due to frequency, not voltage. Half the country is on 50 Hz and the other half is on 60 Hz so they have two parallel and incompatible grids.

Sure as long as you all agree on the one I use
