It potentially IS dangerous to the caster- the only reason it's not REALLY dangerous is because the wording of the spell is such that they can't attack. The commands that force them to move stop them from taking other actions, but I'll point out that in moving and obeying the spell, they have taken an action and thus are not flat footed, even if they weren't the ones to decide on the action. They are still aware of what's happening, and as soon as you stop chain casting the spell to attack them they're going to be able to react because it's clear by then that you're hostile.
Also, sleep isn't one of the things that command lets you do. It's very clear about what actions you're allowed to command: approach, drop, fall, flee, halt.
I'll also mention that if you cast it six times, there's a pretty good chance that it'll get resisted at least once during that time, letting him shout for help. Also, Command DOES have a verbal component.
