On the radical statism -- I guess maybe? At least the in the US right now, we certainly don't have a government that's good at directing money to the most needy. See e.g. the while USAID fiasco. Even if we had a government willing to fund international aid, I still think there is room in the world for people donating to causes they care about. If nothing else, this is how new causes rise to prominence, to be recognized by the official channels.
Compare colonies run by countries to colonies run by corporations for one example.
The difference is that in corporations you don't get to vote on who is the CEO.
And your country can't usually remove your citizenship without a REALLY good reason.
Choosen by elected officials. Consistently underpaid.
As opposed to famously power-awerse and accountable middle management in corporations :)

Think of state like a corporation in which every worker is in the board and has voting rights. Maybe then you'll get it.
