Event Sourcing (2017)

For this specific case, nothing, however let's say you need to know when the user got a specific scope and from who. You probably can answer this question in SQL if you prepared your database to do it (i.e: a changeset table), however in an event sourcing architecture you would gain this information for free.

However, just because you're using event sourcing doesn't mean you don't have a database with the current state of your entities.

In Ruby on Rails one can add just one line of code to achieve the same result.

  class User < ActiveRecord::Base
    has_paper_trail
  end

That solution is good enough for most use cases and doesn't require highly skilled architects and developers to implement Event Sourcing properly.
