人 is less 'person' than 'one body you can count'
The picture One body standing on two feet — a single unit you can count, divide by, and point at. 人 is a person counted one by one; 民 is people bundled into a mass to be governed.

this very body
본인(本人)이 오셔야 해요.

All of it in one picture
人 is one body standing on two feet. Count those bodies to the end and you have population; divide the food by that count and you have portions. Say which land a body stands on and you have a foreigner; let many bodies lean toward one thing and you have popularity. And point your finger at this one body rather than any other, and you have the person themself.
