There's a number of countries with legislation passed or pending (Germany is one) to criminalize doping. Marion Jones spent time in prison for it here in the US (though her case was linked to check fraud too, and that's likely what made her go to jail instead of getting off with community service)

In that context doping is considered damaging to the country's reputation (to my other point) and should be deemed illegal. Or at least until biological enhancements become widespread and the games become too ordinary. :)
