Oh, sure that's not the solution - I don't connect my laptop to cables everywhere I carry it. It's still nice to have wires strung because that allows me to connect all stationary equipment to a cable (IPTV receiver, apple TV, TV, Playstation, VOIP, etc.) and position Wifi APs where they're needed. Cables still provide the best and most stable network, despite all advances in Wifi tech. I can absolutely recommend doing this if you have the opportunity. The cost is negligible if you're about to (re)do the electrical wires.
