Even without a mixing service, there is no way to prevent somebody from sending you tainted coins.

Yes, this is also an important point.

Just picture the following scenario:

Hey, I want to pay you
No way, your coins are related to the recent hack!
I already sent them to your address. U MAD BRO?

It might be ridiculous, but it's totally possible. What will you do then, now that you yourself are tainted too?

WoW, nice. I mean evil.
Just send a few coins to some reputable exchanges/services and done.
Pure evil.

Not entirely true, as that unspent output need never be touched. I can move my other coins which I had in this address to another which is now clean, without touching the dirty dust that you sent me.

It's not necessarily dust. Also, I thought we were marking addresses and not individual outputs.
