Given the effort required to put cabling in e.g. mine is underneath plaster, future proofing it as best you can could save aggravation in the kind of timeframe that people live in houses for.
> future proofing
The best future proofing thing you can do in a living house is lay down at least x2 cable per drop.
The best future proofing is running a conduit, not just copper.
It wasn't that much more expensive and I knew that it was going to be such a pain that I was happy to do it once and future-proof. Probably won't max it out in my lifetime, but it's nice to have options.
