The task may be easy in the word’s literal English meaning, yes, which is part of why it doesn’t generally demand an Easy (in ge game jargon sense, meaning DC10) check to accomplish.I mean the task is "easy". Is that what you mean? Where we might differ is that I am thinking about what that could tell us about the game world, and the nature of day-to-day activities within it.
I don’t think the first view is consistent with how the rules instruct the DM to adjudicate actions. Moreover, it can lead to thinking of the obstacle being the “source” of the DC rather than the task, e.g. thinking of the lock itself requiring a Hard check to pick, instead of considering the character’s approach (using thieves tools) to their goal (unlocking it) and determining that a Hard check should be required for it to succeed.In one view - there is a putative check, but it is consistently waived. In another view, there is no check. What I find helpful about the first view is that it argues for in-world consistency. Whereas the second view creates a mystery - a kind of epiphenomenal ectoplasm - an aspect of the world disconnect from other aspects. For whatever reason - partly intuitively - I prefer the first view.
