I wouldnt say it is a bad thing but I would suggest looking for a bit of balance.
Posives for Turbo include lower risk of accident/puncture, steady consistent pedalling & ability to do sets you struggle to do on the road due to junctions, traffic etc.
Benefits of actually getting out are a more race specific experience, improve bike handling skills, learn to cope with punctures etc.
I turbo during the week but try and get out into the real world at the weekend. It's got to stop raining, sleeting, snowing soon...
