What do you do when the money is gone? With other payment technology you can get court orders to freeze funds, or judgments against current holders.
Bitcoin, on the other hand, is irrevocable and pseudo-anonymous. In July 2011 the owner of MyBitcoin.com web wallet allegedly walked away with 50,000 btc of customer funds. We know where those funds are. You can see them on any block explorer. But it is not possible to freeze or confiscate those funds. And we don't know what real world person or people have access to the keys controlling those funds. So what are you going to do?
MtGox went under with 850,000 btc of customer funds. Its creditors are currently fighting over the 200,000 btc that was found to still be in possession by the company. The other 650,000 btc? Who knows.
It's just a simple fact of reality. If you don't have physical control over the keys for that bitcoin, it is not your bitcoin. Some of us have learned that lesson the hard way.

That is just a limitation of the Bitcoin protocol. One could build a protocol where communities could agree to freeze (not accept) or greatly devalue those funds.
Miners could conspire to mostly freeze certain bitcoin.
It wouldn't even have to be done in a way that was visible on the bitcoin network, they would just have to agree to not include transactions from whatever addresses.
A strong majority could probably refuse to acknowledge blocks including the blocked addresses, which would be a real freeze (rather than the hassle freeze obtained by not including the address in blocks produced by the conspiracy).
You'd need >50% of the miners to do that. It is precisely what I mean by building a protocol.
Of course, without strong consensus (and a real algorithm/protocol) such attempts will likely just result in fractured blockchains (basically the state at the moment, with many competing implementations of the same basic idea).
It is an explicit design choice of the bitcoin protocol (feature, not a bug) that doing so requires a cabal of the majority of the hash power. With properly distributed hash power like bitcoin had in its infancy, this would not have been possible.
