Well then you have to think who buys Dutch goods is it Germany, France etc or is it someone else. If it is Germany and you pull out but they don't you would have to weaken the currency and this would severely affect your banking sector as it likely owed lots by the PIIGS.

If Germany pulled out and you did too you would have to try to ensure the currency was always below Germany but above the Euro. Thats if the euro existed anymore of course, which it would in some kind of form in order to service the debt.

If Netherlands is not exposed to a large amount of PIIGS debt and Germany pulled out then you could pull out take a small hit on debt and then follow the new D-Mark.

edit disclaimer obviously if Germany was not your main trading partner none of the previous thought experiment can happen.
