It's just a lack of decency and common sense.
If your country man can't travel, neither should the King and his family.
In the middle of a pandenic where thousands of Dutch men and women have lost their jobs due the pandemic, the King goes and buys 2 million Euro speedboat.
Willem-Alexander's actions are "beetje dom".
But all could travel. That was the point. It was an
advice to restrict travels when not possible. It was
no lock-down. The royal family actually went to a safe "yellow area" where travels to were permitted, plus they did travel with own transportation to an own secluded domain in a safe and not closed area.
All this while lots of Dutch went on holiday (I myself went to Colmar in France with friends) and in the Netherlands the city centres, the IKEA's, the beaches, etc. we're so full that police had to close off and re-direct traffic.
The King and Queen immediately returned and publicly offered their excuse. That was it. Then it was the time of the End-of-the-Year reviews and the traditional stand-up comedian shows with the one joke after the other was fired about this unlucky Autumn break. That is why this episode came back in the end of the year.
It was mainly fed by (social) media and picked up by politicians with a shortage of attention like Lilian Marijnissen (Socialist Party) and Jesse Klaver (GreenLeft) - not coincidentally both leaders under electoral pressure- aiming to damage the quite favourably polling Prime Minister by attacking him for "poor leadership" by not even able to control the Government (the King is a member of Government).
Royals are meant to be role models. They should be who the public can look to for a good example during this. A vacation to play captain of his boat, when his people are in pandemic lock downs, is beyond stupid.
While its great he supported a Dutch company in buying the boat, its perhaps also not the best time to be advertising spending such money on a Luxury.
I doubt
any Dutch sees their King or Queen, or the princes and princesses as a role model. I am a Dutchman and I have never ever seen any Dutch doing something or
not doing something because of the royal family. That is so typically un-Dutch, following the royal family...
That is also not at all their existence. The Kings and Queens are the head-of-state by birthright. And that is it. How can any Dutch follow their "role model" without a Golden State Carriage, without a safe stacked with glittering parures, without private estates in Italy, Argentina, Greece, without 600 people working for them, without the planes, jets, helicopters, limousines and SUV's at their disposal?
How to follow a "role model" speaking to us in a 17th C Chinese Salon studded with fabulous artworks? That whole "role model"-thing is in no any job description. Otherwise we all are bribing (Bernhard), deny extramarital children (Albert), evade taxes (Juan Carlos), befriend criminals (Andrew) or bitterly fight each other in public (Charles and Diana).
For so far the "role model" of royals, nipping a cool glass of De Nonancourt bubbling champagne Grand Siècle Rosé Millésimé while watching a concours hippique seated in a royal loge.
