The word "more unbound" can mean unrestricted or unencumbered. Antonyms for this phrase would be bound or restricted. When someone or something is bound, they are limited in what they can do or achieve. This can either be self-imposed or external, such as legal restrictions. Restriction can also occur when someone or something is physically unable to do something due to a lack of resources or other factors. Thus, when someone is "more unbound," they have more freedom to explore or achieve their goals, while those who are bound may struggle to accomplish the same.
