I'm not a lawyer but I'd guess that since you're citizen at the time, you'd have to follow the law for renouncing citizenship. You "unilaterally" renouncing it wouldn't mean anything since the law of the country says different.
Perhaps consult a lawyer and if they say that there might be something there try to crowdfund it.
But this is exactly the point. US law specifies what you must do to give up US citizenship. And the US would continue to regard you as a citizen - you definitely put yourself in a position of not being able to set foot on US soil without consequences if you go this route.
But remember, in this scenario you live in the Netherlands. You want Dutch law to agree that you are not a US citizen, thus relieving you of your obligations so long as you continue to live in the Netherlands.
