Currently I don't have something, which really need encryption. However, should it ever be necessary I'd modify after each use the timestamps so it looks like the container was last accessed years ago. Within sensible limits, of course. It would be much more believable to have forgotten a password, when the last access was several month ago than when the timestamps says it was accessed last week or even yesterday.

I wonder if the "no self-incrimination" clauses could help here.

Nope, this is always topped by 'might makes right'.

If the other is used it deletes all the data you really wanted to hide and replaces it ....

Even if you meant it funny... won't work. If your hd got seized, write blockers are used during forensics. Or a bit identical backup is made before something is done with it. They might not be able to read your data, but they are very capable to prevent any data changes as soon as they have the disk.

A few lines of code are all that is needed. Let's call this replacement 'ScumBox'. ScumBox just needs to be a barely working dummy, so that scum always can claim: 'We are not using BusyBox, this is ScumBox, which we adjusted to our needs'.

On the on hand you are right, on the other hand we know thousands chemical compounds and reactions, which do not exist or happen in nature. So just that this reaction does not happen naturally, it is no prove that it is impossible.

This would their government in Washington never allow.

This might depend on the language. Some languages have a more fixed set of grammar and spelling rules than others. As programmer I love to learn patterns, which I can apply to a well defined group of problems. My native language is German. And it is an extremely ugly language when compared with a computer language. Exceptions of exceptions in exceptions in every imaginable grammar and spelling rule. For each exception there might exist a historical reason, but in many cases they don't follow a apparent logic. Many of the mnemonic tricks given by teachers to at least give the appearance of some logic behind those exceptions, are utterly worthless. They all could be compared with algorithms, which works only in 85% of all cases. As a programmer I would not want to rely on crap like that. So in contrary to your experience, most coders I know are much better in computer languages than in German.

And why not? I make most of my money with failed projects and crappy code.

Certainly, yes, but for how long?

Better not. The bar to actually make money with a game, even a simple game, is very high. Might disappoint the kid and rather drive it away from programming.
