I think the big issue is that there is nothing in this that clearly says "you have permission to use/distribute this".

"this software is information" does not achieve this because information can be subject to intellectual property laws! Even excluding that, it's not clear so imposes a legal risk on users.

"It is subject only to local laws of physics" does not achieve a clear grant of permission. It's phrased as a statement of fact, and a statement of fact doesn't actually give permission for a reader to just act as if its true.

There's minor issues too... just use the 0BSD or MIT-no-attribution or CC0 license which does what you want in clear and unambiguous legal language, with the bonus of trying to stop you getting sued.
