Well you don’t want the people who slip through the cracks to wait in line for months to get their money, so you probably need to figure out a system to handle those people, and employees to make it work. Deciding how to handle requests from the people like that, without allowing abuse of the system, and training staff takes time.

I’m sure with research you can find more practical issues that get in the way of implementing it tomorrow, which is before getting to the political issues.
