RE: Coinjoining

Assuming one owns Bitcoin acquired from any KYC source, what value would there be to obfuscating the KYC links? Do you fear a $5 wrench attack from a common thief or hacker trying to steal your coins? My concern is that any government agency (eg: IRS, NSA etc) knowing you've purchased BTC from Coinbase for example, can simply ask if you have used a coinjoining application and why? Will you risk lying to them? If IRS audits you, can they not demand an accounting for the disposition of any coins they KNOW you have purchased via any KYC source? To me, this seems a much bigger risk than falling prey to a non-governmental crook. I really don't see the point of either Samurai or Wasabi.

Change my mind.🤷
