Electrum is just a wallet that does not violate any laws that could allow the government to pay attention to it. There are no prohibited functions in it, only the most necessary things to receive and send bitcoins, also can hold there,
You are right about Electrum, however, both mixers and CoinJoin are not
illegal, but how many mixers have been taken down, and now Samouria which is also
just a wallet that helps bitcoiners enhance privacy has also been taken down. while Wasabi didn't wait for the government to knock on their doors before they shut down their CoinJoin service.
The point here is that the government has opened the pandora's box and they can ban any service and claim that it enhances privacy for bitcoiners, even if the wallet isn't advertised as such. Personally i do not want things to go that far, but i think we may be heading in that direction.
