And it is more practical and consistent with a free nation than having people register to be forced to serve their country. We have plenty of people ready to volunteer to serve our nation, and if we encouraged and trained local militias, or expanded National Guard opportunities and benefits we'd have even more people standing by to serve if needed. And many of them already have the needed skills and background.
Practically speaking the Selective Service registrations are a waste of taxpayer money. The federal government already knows about every child born in the country, and they know the names of all the 18 year olds in the country.
Of course they may not be able to locate them, since young people move around, and if the draft were to be reinstated the federal government would have to figure out how to notify the draftees, but they have that problem with or without the Selective Service registrations. As a practical matter if they really need to round up young people they could just use Facebook and the state licensing databases.
Despite Jeb Bush's stammering response at the debate, the real issue is whether or not to have a draft, and if so whether or not to draft young women for combat. If, as he says, there is no plan to reinstate the draft, then there is no reason to waste money on the Selective Service bureaucracy.
Thank you! You said it better than I did.
