I rent an apartment with double brick walls everywhere. I cannot install cabling in the wall, or really anywhere it's not a severe trip hazard. For the most part, this is fine, because almost every device I own that requires internet access has wifi. (The few that don't, like my NAS, can live next to my networking equipment.)
Your suggestion would have meant that I couldn't connect my Playstation to the Internet, which is a little bit silly, especially given that my scenario is not an uncommon one.
