You'd have a great point there if DNMs accepted gift cards and PayPal. I'll let you figure out why they don't, as a thought exercise.
I don't know what DNMs are, so I can't speculate.

What you're really asking is "why would a government create something it couldn't control." The answer to that is "It obviously wouldn't."
Which means that they can control it. Or have some sort of back door/kill switch/shit we know nothing about but they do.
If that was true, since Bitcoin is open source, then the "backdoor" would reasonably be in the encryption aspect.
And if that is true, only three or less people in the Intel community are even aware of that information and
in theory would only be used during the highest of national interest reasons, such as preemptive attack on enemy
networks or other, prior to a full blown war, such as a World War 3 event.
No intelligence agency in their right mind would risk letting other nations know they can break
a type of encryption on a continual basis, just to monitor worthless information.
Zeroday exploits are always saved for a grand purpose, not for "criminals and nuts".

If you could understand how Bitcoin is a honeypot, it wouldn't be much of a honeypot now, would it?
Yes, but by that example, going to the toilet is a honey pot too, because I don't know how it is one.
