Traders; low information investors; people who are not 100% confident in their personal infosec and not willing to lose their bitcoins on their own.
"Not being seizable" hasn't really worked out for bitcoiners who've been arrested. Or for that matter robbed at gunpoint.
There are plenty of legends of old wallets "waking up" due to the person getting out of prison, as it seems the only plausible way someone can sit on 30 BTC for 10-15 years, through all the news and price movements, without touching it once. One would only expect to hear about the successful seizures law enforcement makes.

This seems orthogonal to the ability to seize assets.
