Freedom of speech (and by extension, spelling) doesn't help with the question of the best "options." You can put a primitive hieroglyph of a sideways bird at the beginning of each written sentence, and they won't put you in jail for that act itself (it might conceivably have implications if it's hate bird speech or maybe somehow in terms of contracts, but not for the grammatical/spelling error itself.
The most important thing, of course, is to be free to speak (and write,) but there is also the threat that what one says and writes will devolve into mutually unintelligible mutterings of madmen.
To prevent this outcome, and without any great controversy, we all accept (then rebel against) grammar and spelling.
If you want to subvert the status quo, you do things like spell "the," "tha," or replace "s" with "z."
If you want to have wide comprehension, you learn the most accepted forms.
The hyphen is often used to make meanings more clear, as in
@Mike the Brit 's observation about "re-signing." I like it. I just don't know that it's standard - that would take a survey of style manuals and dictionaries and the like. But it does clear up the problem of the antonym pair hiding in the same word.
That's a situation we cannot in good conscience sanction, and we should cleave to clearer solutions
