体 is the modern simplified form of 體. The older form combines 骨 (bone) with 豊 (abundant vessel), suggesting the physical framework of the body. The modern form replaces the left side with 亻 (person) and keeps 本 as a simplified phonetic and structural component.
A person 亻 stands beside a tree 本, representing the physical body as the root and foundation of a person's existence.
For タイ, imagine tying a ribbon around your body: tie -> タイ, and the ribbon wraps around your physical form.
