The question, rather, is how many of those registered are actually drafted.
No.
Replace "conscription law" with "death sentence" and see if "how many of those are actually carried out" and see if that makes sense.
A law is a law is a law.
Government MAY not enforce every single law fully as it lacks the capacity or willingness to enforce 100% of laws on the books, but the fact of an existence of such a law shows CLEAR INTENT TO ENFORCE IT.
They reformed the laws several times, yet they kept all elements needed for unforced conscription.
The paper that you cite does not necessarily support the notion of compulsory conscription.
You are missing the point of that citation. Reread my comment above again.
The paper lists MANY examples of circumstantial evidence of an existing and ongoing conscription.
What it DOES NOT DO is prove a "de facto" non-existence of conscription and an existence volunteer service in its stead.
BUT, it tries to argue such a position, despite the COMPLETE LACK of any evidence for its thesis.
I.e. It's bullshit.
And I'm not citing it as a proof of existence of conscription or volunteer service or non-existence of either, but as a source of that unsourced and unsubstantiated bullshit claim.
I'm not sure what your link to the Taiwanese kid story is supposed to prove
Again, reread my comment.
It is there as an example of tactics and means for deferment available to the urban population, and NOT available to the rural kids.
Taiwanese kid could afford such a stunt at 24 - i.e. 6 years after he became eligible.
For 6 years he dodged the service in the country you define as "one where conscription definitely does exist, and people are drafted against their will."
A rural kid of 18, trying the same dieting technique, would just be written off as underfed because he's from a poor village.
Older than average, emaciated kid among the group of well fed city kids 6 years younger... clearly he's sickly and incapable of service.
He probably even looked at least 30% older than all the other recruits.
And a city kid gets that 6 year buffer cause he has a high school right across the street and a college two blocks away.
Unlike the rural kid who probably walked couple of hours to and from school IF there was one that near, and who could never afford to go to a college unless he was exceptionally intelligent and studious so that he would get a scholarship to a college somewhere in the city.
While the rest of his class went off to serve.
