You're replacing one single point of failure with another.

Personally, my network gets NTP from 14 stratum 1 sources right now.
You, and the hacker, do not know which ones.  You have to guess at least
8 to get me to move to your "hacked" time.  Good luck.

Redundancy is the solution, not a new single point of failure.  GPS
can be part of the redundancy, not a sole solution.
