I don‘t see the argument here. What you describe is sexual harassment and should be illegal.
I believe people should be allowed to wear the glasses they want.

The one thing quantum computers are (currently and theoretically) able to solve efficiently is the factorization problem, but are very much limited by low qubit number, i.e. engineering problems.
Do you consume meat or dairy?
1. stop buying meat
2. stop eating meat
3. stop buying dairy-based products
4. stop eating dairy-based products
5. stop eating eggs, honey, fish
6. use public transport, if possible
7. don‘t fly, if possible
Congrats, you now are an environmentalist.
As far as I know, image based steganography usually uses random noise added to a cover image and a preshared key to decide which noise is actually encoded information. Since printers and scanners are a lossy channel, the noise will deteriorate. So I think this is a hard problem -- this might be possible with some kind of error correcting code as used in QR codes and alike (or maybe even use QR codes as the cover channel)
