Look at AFC Wimbledon, it's an incredibly well run organisation that got a lot of support from locals in one of the wealthiest parts of the country.
They are sitting in League 2 after 21 years of tireless, organised work devoid of infighting and with everyone pulling in the same direction. It has significant financial problems having mortgaged it's own future to build a stadium and has relied, more than once, on donations and loan write offs from investors.
If you think a trust for SWFC could come together in the same unified manner then we too could be a struggling league 2 club, unable to compete financially to go higher for the foreseeable future.
