I was wrong. More homework showed bitcoin foundation tried to do that:

The strong objection of blacklisting theif's bitcoin address is I guess two-fold.
First, the community wish to maintain anonymous nature of the network at the cost of tolerating thefts, or accept losing some justice to get some freedom, like the early U.S. (There are so many bad stories of U.S. outside of U.S. - it's hard to see if now is better)
Second, the foundation has not done enough positive things to let the community believe that when they do negative action it is in the postive interest. If the foundation did a lot of services (there are a lot missing!) since it receives donation, the comunity may be softened a bit.
Not sure if my reading is correct.
That sums it up. A few comments.
1> we don't just get freedom being a currency that does no invalidate based on history. it is about a currency being a currency. if i hand you a dollar, you need to know it is worth a dollar. but, if there's a chance that the dollar once worked, but is no longer a valid dollar because it was stolen by someone before i had it, then the dollar is no longer worth a dollar to you. if there's a 10% chance it is an invalid dollar, then it's only worth 90% of a dollar to you, because that's the odds it is valid. currency must be fungible. a dollar must be a dollar no matter what its history.
2> if you begin invalidation, then you create power structures that are no longer decentralized, because someone has to decide which coin needs to be invalidated, and which was doesn't. you just eliminated the decentralized nature of the currency, which requires another decentralized currency to take its place. otherwise, bad powers will arise and do stupid things in addition to erasing fungibility, like stopping mothers from getting $150 to her son for his baby's diapers.
3> have you heard about the good stories resulting from US freedom?
