Community colleges with regional accreditation and freely transferable credits are not a problem. They serve several niches that large universities may find inconvenient or unprofitable--such as the hobbyist courses you mentioned, continuing education requirements, and remedial courses for students with inadequate high school education, and compete with some larger universities for the non-traditional students.
Spending some years at community college before transferring to a larger university's degree program is a great way for poorer students to save tuition money, and for academically unprepared students to catch up to their age cohort in a reasonable way. The disadvantage lies in the social networking, which is a big part of the value of (4 years of) on-campus university education. At a community college, it is somewhat less advantageous to make contacts with other students and professors, because they are less prestigious overall. Someone with an associate's degree is not as likely to help you get a job (at least for several years after graduation).
Most for-profit schools lack several of the elements I consider to be absolutely essential to qualify as a "community college". Many of them appear to be so horribly parasitic and exploitative that I can't figure out how they manage to get so many students.
