I mean, one could but one would be wasting a potential earning opportunity to recover electricity and equipment costs. The SETI project will even take Gridcoin as a donation, so you could put earned Gridcoin back into the BOINC projects and help to support projects financially as well as computationally!
How much does a BOINC project cost to run?
The budget of a project like SETI@home is close to half a million dollars US. If you are BOINCing without Gridcoining then you are wasting a chance to financially support the SETI@home project.

Yes, the unfortunate side is that you will have to leave your BOINC team but I believe there are plans in place to remove the team requirement. I also personally think that there should be an internal leaderboard within the gridcoin client to do stats tracking on internal teams within Gridcoin, at least as a temporary measure. However these features have not been implemented yet.
