What about a solution that makes it easy for any small group to hire lobbyists? Something like Kickstarter campaigns for cause areas where you want to get something done (eg. prison reform) so you create a campaign and get people to contribute; it hits a minimum threshold and the platform hires a lobbying firm to work towards the goal. Of course, with lobbying there are no guarantees anything happens, but would be interesting (sorry this isn't very thought out, I'm just reading the threads here and this came to mind)
