I'd say on most DRM measures, yes, but being online all the time can be an issue for a much larger group than a disk check, or invasive software, or even an initial online activation.
For example, my PS3 has a spotty connection. It's too far from the router. If I could never play games unless I had a connection, it would be a worthless device. As is, it usually spends a minute trying to connect and then tells me certain services are not available, but the game itself is fine.
