Definitely best policy but there is not much you can do if one of your best players like Houston wants to go home. You just have to make the best out of it.The best performing teams like Brisbane, Geelong, Richmond and recently Hawthorn get there by trading in quality.
Not by getting good returns for quality that leaves.
They lose the fringe players seeking opportunities and get paid handsomely for them due to their success and keep their quality whilst adding more.
There's no point "winning" on trades out like Wingard if it just keeps your list forever building and never getting there

Even the Brisbane Lions juggernaut had Des Headland wanting to go home after a GF win.
