You're disappointed because you didn't get Iron Man vs The Con Edison Man
If Thanos and Ultron were walking through Manhattan you'd have point. This is Kingpin and nothing he's doing should be out of Daredevil's capacity to handle. You're treating the power going out in Manhattan for a little while and a ban on vigilantes like a cosmic level threat. This is lightwork that doesn't require a crossover event.
Y'all take these comic stories too literally. Sharing the same universe doesn't mean they need to make an appearance. There'd be no character struggle if more heroes outside of this assisted. The point is to see Daredevil fight through this. He has Punisher to help because he's another street level hero who interacts with DD. Frank and an injured DD took out a bunch Kingpin's "army" already. They'll fight them off and eventually expose Kingpin's scheme at Red Hook. Money laundering isn't an Avengers level that.
You're also playing dumb by acting like you don't understand the business end of it. They're not bringing RDJ, Evans, etc into a TV show. We all know that going in so bytching about not seeing them is a problem of your own creation and not a narrative issue.
