If your security requirements are such that you need to worry about legally-issued search warrants, you should not connect your computer to the internet. Especially if it's running Windows.
Right, this is just a variation on "If you have nothing to hide..."
ETA: You're not wrong; folk who have specific, legitimate opsec concerns shouldn't be using certain tools. I just initially read your post a certain way. Apologies if it feels like I put words in your mouth.
Because all cops are honest, all warrants are lawful and nothing worrying happens in the land of freedom right now.
Appeal to the law fallacy.
In the modern political environment, everyone should be worried about that.
