It could be a slippery slope. That's why the point is not to just accept it and move on, but to comply while pushing back against it.

And complying right away, but with a bullshit field, is a good way to signal "we do not agree, and we're going to always find a way to fight back".

Taking a hit to avoid defeat, does not mean surrendering. It just means that you need to recognise when a battle is lost. In a way, the other side of the slippery slope is the sunk cost fallacy, where you refuse to admit that something is a lost cause and you keep on pushing, making things worse.

It's a matter of balance and reason, which people nowadays reaaaally struggle with.
