I don't agree. Abstraction is actually an indispensable tool for coping with complexity, and enabling cooperation. How can anyone make a decision about anything (like what's going to be for dinner tonight) if they insist on first understanding all involved factors down to the level of elementary particles (and everything - everything! - in between).
If anything "has to go" it would be secrecy: one needs to be able to inspect / test any-thing reportedly underlying a phenomenon / service / claim. However even that is not always feasible, e.g. I wouldn't want criminals to spy on me, take the money, and run - "the enemy" to disrupt society / abolish the rule of law / trample dissidents, for that matter - would you?
It's a very real dilemma: sometimes we just need to trust others / authorities / "the process" beyond a certain point, and may be disappointed eventually; but if we don't, things could get far worse. So we need trust-enhancing mechanisms - a free press, a privacy authority, corporate reputations, open source platforms - and even those may turn out wolves in sheep's clothing. An ideal world isn't in sight.
