Well for example, and I'm not advocating for these ideas other than pointing out that they'd be much simpler than changing the structure of society: the Government could either buy, or forcefully take control of, Wikipedia, or they could create a competitor with enough funding to take over. They could do it creating a gov department to run it, or they could set it up as an organisation fully owned by the state. They wouldn't even have to go that far, they could just pass a bill that would send however much money from taxpayers to Wikipedia every year, or as a one-off to create a new taxpayer-funded endowment. There's lots of changes to society that I think would be good, but "ability for government to decide to spend taxpayer money on a charity like Wikipedia, or to create their own version in-house" isn't exactly lacking from the current system.
