The only problem with this is that for some god-afwful reason, anything built before the 2010s (?) placed electrical and phone sockets at hip level instead of ankle level. So you're staring at ugly sockets all day.

So sadly you still have to punch holes.

Then again, it isn't that much of a bother if all you have to do is punch a lower hole, relocate the socket and then plaster both holes up and repaint. Especially if you make it a weekend job to do the whole house at once. Or rather, the way I look at it is that it's a weekend job that will improve how the house feels for decades. Doing blind wiring (gutters) for all the ceiling lights falls in the same category.

I think electrical/phone sockets were placed at that level because many telephones were designed to hang on the wall (docking onto and covering up the faceplate) for easy access. My childhood home had one that we used this way before we got a landline.

You can always put a blank plate over the old one and save yourself a mess of plastering.
