Not zero benefits. In your system run by people your money can be frozen or taken away without your consent. Recent example: peaceful protesters in Canada. There are also tons of examples, when scammers would reverse a good transaction after receiving the goods.
Another benefit of some blockchains: incredibly low transaction fees.
Another benefit: smart contracts.
I don't understand why you need to straight up lie.
As a Canadian, and a former Ottawa resident, I can assure you those were not "peaceful protestors". I had friends and family who had to leave the city to escape the unending noise, the harrassment by the 'protestors'. There were arson attempts, assaults, threats, and general disregard for the law.
I've literally been a peaceful protestor in Ottawa (I was a student there after all). There's a serious difference between a daytime march for a cause and what those people did.
They're criminals, and were treated as such. I'm fully in favor of the government being able to seize the financial assets of criminals.

What benefit do such contracts hold over actual legal contracts? The biggest difference is that when legal costs have bugs, courts can resolve them.
BLM/antifa protestors burned hundreds of buildings, murdered at least 26 people, including children, harassed people in the middle of the night, tried to declare their own autonomous zone where they robbed business owners. And many people call them peaceful protesters.
Canadian protesters limited their noise to 10pm, didn't burn anything, didn kill anyone. Noise is what I saw from hours of footage. I didn't see harassment, maybe it happened, but it must have been an exceptionally rare thing.
