You go soldier. You still haven't explained how this freedom you describe was ever in jeopardy of not being an option for you but whatever. Onward Soldier. Keep fighting the good fight. And keep protecting freedom like you do for all of us. 
I am not fighting for anything. From the replies, that is you who "defend" absolutely useless for music hardware sticks.
But if you want to know from where my opinion comes:
I am not a "pro" in music. Sonar Platinum has reverted itself into demo once even for me. Not at critical time, but that was rather disturbing (you can find my angry post about the issue...).
As a computer "pro" I never use a single peace of hardware/software for anything critical as long as that is theoretically possible. In practice for any "stage like" job that means at least 2 computers.
2x(or more) online authorizations allows one license for both systems, primary and "hot spare". And these systems are completely independent.
With one dongle even with 2 computers there is still one point of failure. So in case I will start to use any "dongle ware" for real job, I will need to buy 2 licenses and 2 sticks.
For hardware (raids, disks, servers, routers, etc...) I do this. But for hardware there is a good reason for that (including the fancy fact that 24h replacement guarantee cost close to the unit price...). But for a software? A hardware copy of "bits"? Here I see no reason at all.
