Then if you believe in the rule of law (in germany we say "Rechtstaat") and the presumption of innocence, it is kind of a civic duty to follow these steps. If only to oppose this line of thinking. Or even better, bait those who would like to control us into openly acting. Especially if you are a lawyer, have enough money to pay a lawyer etc.
I will probably piss myself and cry if I ever really "become a target" as it happens in China, cartel controlled parts of south america, dictatorships etc. But I will be damned if I don't make some kind of token resistance to us going down that path if all it costs me is keeping my privacy and maybe having legal hassle+ cost of replacement if my stuff gets seized.
Even if you think you're doing everything right, once you're targeted by LEAs they'll find something.[1] Even if they find nothing, they can make your life miserable pretty much indefinitely or until you run out of money for lawyers.

It's not just techies or criminals that want this level of security: companies also want to keep things secure, trust me. In the oil rig industry we used TrueCrypt to secure (1) employee/vendor lists, and (2) location scouting information. Given how difficult it is to obtain tis information, competitors would pay big dollars for this information, regardless of how obtained
Hiding non-suspect behavior is, for everyone watching, the same as hiding very suspect behavior. If you do this and make a single mistake (anything really, speeding could be enough) there could be a red flag on your file that makes sure your possessions will be searched (and possibly taken) and be prepared to spend some time in jail.
I get it, everyone should be hiding all their activity online so that hiding your activity online isn't suspect behavior. But I really don't think that will ever happen and I'd rather be an open book about all my behavior then try to hide as much as possible while becoming a target.
