Mandated national service on the idea that you as an individual “owe” something to society is a perfect example of the Left thinking the State has superiority over the individual. To them there is no concept of natural rights. To them all rights are bestowed by the State and you “owe” the State.
Rand is right. You are not born “owing” the State. The State has no claim on your rights. They are yours inherently.
Rand didn't write this, Ron Paul did. Unlike his old man, Rand supports fighting ISIS. But I agree, Ron Paul is right in his conclusion, if not all his premises.
