This premise can't be done quickly in the US, and it's bordering on comically absurd that anyone here would dare to suggest otherwise.

The US bureaucracies, federal and states, and the criss-cross between them, is extraordinarily large, complex and inefficient. The US Federal Government all by itself is a spending machine larger than Europe's biggest economy.

To pretend a system like Togo's could be implemented quickly in the US, one would have to pretend the US government system isn't presently constructed as it is. It would be necessary to invent an elaborate fantasy, where you start from a blank slate and have to deal with none of what presently exists.

And every time you say it, you're almost certainly wrong if it's about anything but a proof of concept. Every single "I can do that in a weekend" post I've ever seen basically ignores all the complexity of software development and would result in a completely useless system except for, at best, the optimal happy path.
