It is a limitation, but when your other choice is "not working at all, pain, depression, despair" having to work at home is the least of your problems.

I have a grimmer point to make: Working out of crappy half-assed "startup incubators" with lousy desks, lousy seating, and an atmosphere flavored with stress was a direct contributor to my own RSI problems. You might not want to wait until you have symptoms to conclude that having an actual desk and some quiet is a good idea.
