To add on to Steve Alexander's post, lots of online interaction these days can be done without leaving home. To OP, why waste the money renting an office if social interaction is what you want? Forums like elitetraders are free.I think it depends on your personality. Some people need social interaction; some don't.
A better reason would be to look respectable. Working from home makes one look like a jobless loser. Working from office makes one look gainfully employed.
