copy note

For distributing my work, I would like to add a note that conveys that I have no problem with it being used, copied, etc.

The note should

• not stifle or slow distribution
  If this were the only goal, I'd just use an established license. Rolling an own causes uncertainty for authors and users.
• not rely on the concept of intellectual property
  The concept makes little sense.
• be short and pleasant to read
  It should not contain any foreign concepts, simply stating that I am happy with people using the work.

good established copy notes

0BSD

Seems to be legally sound and short:

Permission to use, copy, modify, and/or distribute this software for any purpose with or without fee is hereby granted.

THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS. IN NO EVENT SHALL THE AUTHOR BE LIABLE FOR ANY SPECIAL, DIRECT, INDIRECT, OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, WHETHER IN AN ACTION OF CONTRACT, NEGLIGENCE OR OTHER TORTIOUS ACTION, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE.

• Unsure if "permission" implies that permission was required in the first place.
• The ALL CAPS AS IS CLAUSE is eerie.

Blessing

Is pleasant to read.

The author disclaims copyright to this source code. In place of a legal notice, here is a blessing:

May you do good and not evil.

May you find forgiveness for yourself and forgive others.

May you share freely, never taking more than you give.

• Arguably, it reinforces copyright by mentioning it.

So, the one I'll use for now is this:

Use, copy, modify, or share the given work freely for your own good or the good of others.

Find forgiveness for yourself and forgive others.

Take no more than you give, lest you loose, though, no one is keeping score.
