Incorporation doesn’t say anything either way. The fact that the first amendment didn’t apply to the states until it was incorporated via the 14th says nothing about whether it was initially viewed as a collective right or a personal right. Same for any other right in the bill of rights.

Most evidence points to the fact that the second amendment was viewed from inception as an individual right. Especially if you look at the state proposals for the second amendment, which allow exceptions for things like individual circumstances (e.g. people who had participated in a rebellion).
