No, it really is. Some of those people are heroes. Now, there are some fictional and legendary heroes who dont. But, you see, such fictional and legendary heroes wear something called the cloak of the protagonist. It means that they always succeed because we tend to tell stories about heroes who succeed as opposed to heroes who fail. In D&D, while you do play a protagonist, you do not wear the protagonist's cloak. Instead you exist in a network of probabilities. You, as a player, decide how you want to navigate those probabilities. When the dice are favorable the story plays out like a legend in which the hero succeeds. When the dice come up with failure, the story turns into a more modern take on the hero in which heroes are filled with frailties, weaknesses, and are as prone to Murphy as anyone else; sometimes things just don't go their way. There is no good reason why that should not be the case. You may as well argue that heroes should never miss, auotmatically succeed on DC 35 skill checks, and never be prone to death. The chance of failure is what keeps this game exciting. Removing that chance from DC 5 skill checks during stressful situations effectively removes such skill checks from the game.
Meanwhile, if you really want to be a hero who cannot fail at lower end skill checks (as opposed to playing a hero who is very unlikely, statistically speaking, to fail such skill checks), even in a stressful environment, then take the required feats. Then at least the DM can justify keeping those skill checks, as while you can autosucceed on them you do so because you have spent resources to do so. Or, if your entire group wants to damage the bounds of the accuracy system, use the module in which skill dice are not rolled and a static mean modifier is used instead.
Either way, the story really is over. Because, fact of the matter is, there is not a single good reason to move away from the skill dice system as the standard model. They are more realistic, work better with the bounded accuracy system, and can easily be replaced with a static modifier module for those who really want to for whatever reason.
