Probably just through federated user authentication and information distribution to various free genealogy resources.
There's so much locked away out there behind for profit companies like Ancestry that limit some users' abilities via cost to find their roots. Then there are places like WikiTree, which are great and free, but the wiki model seems like a bit of an awkward (and centralized) strategy for sharing that information.
If the goal is to build One World Tree, a certain amount of centralization will be necessary.
Nevertheless, I would be interested to see if something like a federated version of webtrees would be feasible. There would be challenges, particularly regarding privacy, but I think it could be possible.
