Despite the fact that the United States is not a Schengen participant, so that doesn't equate into their rationale for the visa process with those countries, the work that you say the EU should do (otherwise it's hypocrisy) is nigh complete[0,1,2]. The issue is that the United States has agreements with the EU and, much like when Trump tried to negotiate a trade deal with Germany[3], those deals supercede any deals that may have existed with member states in the past. This scenario, when reversed, would be akin to the EU having a deal with the United States but excluding Texas and requiring all Texans to officially apply for and receiving a visa before travel. Even though they're Americans and the deal with America should supercede, they would be - willfully - ignoring it.
