Provably false. The words at
http://phrontistery.info/favourite.html are "correct" and generally unknown by the public at large. Some words grow in popularity (such as "labelmate" and "manga" and eventually get put into the dictionary along with other perfectly cromulent words.
By your own logic, in order to be included in the public record, it needs to have widespread use first. That means widespread use of "incorrect" words needs to be acceptable for the language to evolve. Since language is clearly evolving, you may want to rethink what you mean by "correct". I do not think it means what you think it means.
False equivalencies. The majority of these words are not and have not ever been adopted into modern English, for one. At one time, they *were* common, which is why they were recorded and put into use. If they were not common, they were at least created according to specific linguistic rules - such as Boustrophedon. My problem with "boni" is that it is based on a misunderstanding of proper language rules, rather than the actual rules. As I mentioned, it should properly be bona -> bonum.
Bonus to boni is a gendered construction which indicates a grouping of *good men*, not additive values.
As to the remainder of these words on the site you linked, they identify specific things. A liripipe identifies a
specific thing and therefore must be used to identify it, much like saying "I like that
katana" identifies a particular type of sword. Calling a
katana a
ken may also be correct linguistically, but deciding to call it a
japachopper does not suddenly become correct when twenty others decide to use it. At least not until such time that those twenty people become twenty million.
(Labelmate, for the record, is a trademark like Xerox, and therefore is a proper name and *must* be considered a real word consequently.)

I will add this: dictionaries are not special. They do not determine, prove, or dictate what's 'real', 'right', etc.
Dictionaries recognize and codify accepted public speech. They are determinate in that they react to public language *use*, and thereofre dictate what is "right" far more accurately than personal opinion. And that is why they are valuable in the context of this discussion.
