By removing Smallville and Metropolis, however, you're also removing millions of people. Including other heroes that originate and operate out of Metropolis, which is the size of NYC. I get and completely support removing the memories and knowledge of Superman/Clark's existence from everyone, and even Krypton as the public would never know of it without him, but to also rid two locations, one of which is a major city, I think is a tad much.
