Why not? Well:
1. You don't have a hope in hell of raising several million pounds to buy the club from fans
2. Even if you did, that one-off injection of capital wouldn't raise a penny towards future running costs so it would be another disaster waiting to happen
3. Where is the squad of dedicated and able business heads that would be heading up the bid, voluntarily running the business if acquired, and funding it year on year (same as any other owner has to do)?
A complete and utter non-starter, unless severely rich people come along. And if my a miracle some such appeared, they would want to buy it, not run it for free as part of some weird committee.
