This is really cool.
However, LSB is the most famous method of doing steno, so if you actually have something to hide this is probably not a good method, as everyone knows about this method.

I didn't check the code corresponding to the submitted article, but I'd guess it would be infeasible even for an advanced or even state adversarial actor to automatically check lots and lots of images (unless there is some kind of "signature" that can be detected) just in case there might be some LSB-based steganographically hidden secret inside.
If the adversary is doing a targeted attack against an individual/group of individuals, it might be more feasible, but then I'd wonder if other means of attack, including the good old monkey-wrench-to-the-knee aren't still more efficient.
There is.
You're right that the encryption probably can't be overcome. The risk is more that it is detected and then the adversary beats you up until you hand over the password.
