The reason Orlando shouldn't trade Dwight Howard?

Everyone is afraid that Dwight will leave as a free agent and Orlando will get nothing in return but I think Otis Smith should keep Howard and try to build a contending team around him. The reason I think this is because Dwight Howard will have nowhere to go when he hits free agency. Where is he gonna go? Sacramento... Minnesota? I mean the only teams I think that would make sense to go to would be the Knicks or Lakers but both of those teams are over the cap and wouldn't be able to sign him. Orlando shouldn't panic. They should just try to keep adding pieces to their team.
