There is, or should be, more to academia than just the pursuit of money.
Unfortunately, the current ecosystem of journals is to a significant extent failing at that. Possibly introducing a clear [0] profit motive into that system would result in it working more efficiently and better serving academia's primary goal.
[0] I say "clear" because a lot of the current system of journals is primarily driven by profit motives that are only slightly veiled. There are notable exceptions to this, e.g. PLoS, Journal of Statistical Software, etc...
