Right now there is no non-violent path to achieving that because Taiwan intends to violently and militarily resist if it comes to that. Probably with the aid of America, although I’m a lot less certain of that than 5 year ago, and it’s looking like it’s a lot more likely to be with the aid of Japan as well.

Also a success by the PRC would still result in the political destruction of the Republic of China and the subjugation of its people.

China wants to destory Taiwan's democracy, as OP said quite correctly.

By force. Because Taiwan doesn't want to be a part of Beijing's China.

Come here, chicken. I don't want to hurt you, I just want to eat you!

Become a part of a country with no freedom of speech? Yep, that's destruction.
