Do we have any further proof of the authenticity of the puzzle, other than the image being designed elaborately and the outputs still being unspent after years? For we know:

Transaction was made on May 2020.
First appearance of the image is on Reddit by /u/stsh_n on October 2020.

The transaction also had another output of 0.05 BTC, which is still unspent today, but not mentioned as part of the puzzle in the Reddit post.

Regarding trying the combinations, it's pretty much infeasible. If the puzzle is authentic, there has to be an absolute pattern in which you can gather the words and their order. You can come up with so many different words even if you look at clues appearing in the image. I believe the first reasonable step would be to come up with where words come from or how to get them, and then their order, and evidence of the system working.

It's been way too long since the puzzle was shared. The puzzle creator should sign a message and verify the address is in their control. There's all sorts of symbolism and hints and clues pointing to decentralization, injustice, modern world problems, but the lack of a signed message proving the ownership of the given address makes it less believable.
