Apologies for saying it this way but this is a very naive take. How long did it take for the Vietnam to resolve in the 50s - 70s? How long did the Berlin Wall take to come down, or the Soviet Union to collapse? What about apartheid in South Africa? How long before Ukraine's population can live normally again?

"Change the government" is a process that even in the best cases takes decades to resolve. Children are born and grow to adulthood in these chaotic situations, and that's normally with outside pressure applied. No the tech won't resolve the core problem, but it will allow people to get bread and milk from within a hostile system until that core problem is resolved.
