Help or more dystopian government control ?

Austin , Texas is piloting a program for putting the homeless population on the blockchain. Sounds great and great for society in general. There are some others around the globe attempting something similar.  There is a huge need for poor people and affordable housing as well as homelessness in many many cities and rural areas.  

  But will this be a program to help the homeless or a pseudo subtle attempt to control and know everything about everything and everyone by government agencies and corporations ?  

I used to think a blockchain ID system was the perfect use case for many verticals and industries.  Now it's starting to look like another attempt at control by your typical governments and mega corporations.

  Will it help the homeless or just be another tool to control more people?
