Is there any reason for such claims or are you just dreaming out loud?

This idea that blockchain is gonna be used everywhere doesn't make much sense.

Blockchain is a slow and expensive database. Unless you have a very specific problem that blockchain will solve, it shouldn't be used. In most cases, blockchain is not applicable to the problem.

I so t think governments are going to use it everywhere to become more transparent.  There are other way to become more transparent,  which are less expensive.
