Sure, no problem if it works for you. When i was younger it certainly worked for me too, but i now see alot more value in being able to talk to other like minded people during the day, where talk doesnt mean sending messages to an irc channel. That said, i am by no means extroverted and like being alone but i believe that things like working culture, team spirit and motivation are alot easier with people in the same room. Also depends alot on the company, for startups i think its essential that the core team shares the same space, while a corporate programming job an easily be done remotely.
