Thankfully my coins are clean so whitelisting for me would only be a disaster insofar as it would destroy any reason whatsoever for anyone to used Bitcoin and thus the solution (and my stash) would eventually die. I'd either cash out before it dawned on people that Bitcoin was useless, or hope that a following system would start out where Bitcoin left off vis-a-vis a value base. Probably some combination of both.
i'd bet you have a few of MyBitcoins theft in your stash:
https://bitcointalk.org/index.php?topic=548508.0Most people likely have MyBitcoin stuff (I've not read the link yet.) I personally probably have a fair number of BTC which are closely linked to the allinvain (purported) heist. Word is that these were up for sale on Tradehill-I at the time that I was doing some significant acquisition. But I also have the records of my interactions with Tradehill, and the records of my interactions with the IRS when I paid my taxes.
When tainting pops up it will probably be in the form of white-listing and will probably afford the benefit of the doubt to hodlers. Especially old-timers. As long as Gavin does his job and Bitcoin can be controlled, there will be no reason to destroy Bitcoin and many reasons not to since it is actually quite useful to people from all over the spectrum. And if the (false) idea that Bitcoin has any particular value when it has become a less convenient PayPal can be preserved it could also serve to detract from interest in real solutions which do have value.
the thing is, the gvt is not going to get involved in a situation where drug dealers steal coin from other drug dealers and then try to sell them off on an anonymous exchange in Bulgaria. they only care if they themselves can get their hands on the BTC which in this Evo case, they cannot. so they'll just let the community shoot it out and the final result will be just like every other theft in Bitcoinland since Day 1; nothing.
