Its possible to do it for periods of time, so people will train themselves to do it for extended periods. Even if not infinitely, its not hard to do it far enough from someone to be safe, then do it again to another safe spot. Theres no way to truly regulate it without Tournament Officials assigning staff to watch every single Meta Knight player to deem whether or not they're stalling with it.
The obvious reason to ban it is stalling. I'll give a quote though for the second reason.
"This is the second reason why this tech should be banned. This is the other use that you would use this tech for: to get out of a sticky situation. But this is why I believe it should be banned and this will be the aspect that will probably be argued most.
If you get really deep into brawl. You will realize that its a position battle. By taking advantage of your position and the enemies position you can win the battle. Position matters b/c depending on where you are on the battlefield you will have more or less pratical options.
Generally if a character is in the air and the opponent is attempting an aerial clash they all have the pratical options of air dodging the attack, attacking with a better move, jumping and avoiding conflict, or FF'ing away. The attacker knowing the person in the air has only the following four options can then use a move that will take advantage of as many of these options as possible resulting usually in damaging the opponent.
In the same way if a character was being pressured towards the edge they now have very few options that are pratical: Spot dodge, attack, roll, jump away. The pressurer is forcefully eliminating all other options the opponent may have by forcing them towards the edge. However, if you add in MK's new infinite cape then you give MK an undeniable advantage in terms of position warfare.
If he was being pressured towards the edge, he now has the ability to teleport anywhere on the stage and reset the position advantage to neutral or give him the advantage. There are other moves which can shift an advantage like the move counter, shield, spotdodge, any move with an invincibility frame like wolf's reflector. However, these are not broken b/c they are either available to the whole cast: shielding and spotdodging, or their ability to shift an advantage comes with some disadvantage: counter, long post lag, reflector short range and invincibility frames don't last that long.
However, MK's infinite cape defies both options, not only is it character specific but there are almost no major disadvantages in doing the move, as you can get as far away from the opponent as possible to prevent yourself from being in danger of taking damage. MK now has a clear advantage over everyone else. As a result I believe MK's infinite cape while nonetheless cool to watch and an amazing discovery is unfortunately too broken to be allowed in competitive play.
That and I'm sure M2K will find some way to abuse this"
Pretty sure the last line in that was a joke.
Congratulations. Meta Knight is now broken and is the first character in Brawl to be receiving a technique ban. Something like this simply can't be used in tournament play or it will result in a Meta Knight onry game. It's impossible to viably enforce.
Oh, and someone from AllisBrawl has already trained themselves to do it for 8 minutes straight. Which is the standard tournament matches time limit.
