Even ignoring the very valid points BlackHatCoiner and n0nce have made above, there is absolutely no reason to think that this will provide protection from government sanctions. We have seen absolutely no mention from anyone - not from government, authorities, financial regulators, centralized exchanges, lending platforms, blockchain analysis firms, literally anyone - that once Wasabi start blacklisting and censoring that all outputs from Wasabi coinjoins will be treated as completely clean as if they have just been mined. And given what we know about what the government and authorities think about bitcoin and think about regular people having privacy, I think it is incredibly presumptive to expect this to happen.
