If they're buying milsurps just to have something to shoot, you're probably right. But milsurps are cool rifles in their own right and generally more fun at the range than one of these would be.
My favorite deer huntimg rifle now is a nicely sporterized 93 Mauser in 7x57. I'm going to give this Ruger I have coming a try, but I highly doubt it'll displace this sporterized Mauser to me.
