Here's why Nintendo shouldn't make a new Smash, Kart, or 2d Mario for Switch

This is a yes and no situation.Yes because of the reasons you listed.Both games are probably the best games of each franchise, and have far more content than either franchise ever had.But I think that, if it were made into a platform, it would hurt the franchise in the long run.Or to be more acurate, it would hurt IF they are release as enhanced ports and not new entries.

I think the best solution is to have a Mario Kart 9, Smash 5, and a new 2D Mario.But make them a platform as long as the Switch lives.Or in other words, it would be a new smash/Mario Kasrt only once in a system life, and it would be adding content constantly over time.The difference betwenn my idea and your is that:

1.Making an enhance port would prejudice the franchise growth, in the sense that it would be the same as the last game and thus either get a bad reputation because of it or people not buying the game because they already played it, and hurting the Switch in the long run, since there wouldnt be any more entries on those franchises for the Switch.

2.They need to differenciate the game, and by extention the Switch, as being a new and better console.Making enhanced ports would not do that job that well, and thus could be more of a prejudice than a benefit.

Just a side note, I personally dont think the Mario Kart and Splatoon are enhanced ports.You can only enhance to a point before calling it a new entry.If it has too many new features and feels like a different game(which Mario Kart switch seems to be, with the double items and the (I assume) better battle mode), then it is a different game.
