How do you 'automatically merge' a comment where a user voices a popular concern? What about a merge request that needs to be rebased? What about a merge request that requires deep knowledge of the project to understand if it would break something critical, or introduce security flaws? A nation state could submit a merge request to the Linux kernel that is a blatant backdoor and override maintainers by just shear numbers of 'supporters'? This is a very bad, no, terrible idea. Code merges should not be an open democracy with no opportunity for oversight.
