The correct answer to this open question is the following.

Although there are no options attached we can say the following.

Why would a monarch who is trying to restore his power say something like this?

The monarchs of those years thought like that for the following reason. They wanted to keep total power and control over their land and subjects. They feared any rebellious movement that could mean a confrontation to their authority and power because these kings knew that they could lose it.

That is why Prince Klemens von Metternich of Austria said "The first and greatest concern for the immense majority of every nation is the stability of laws, and that they never change."  The more stability in its kingdom, the better for the king to preserve his dominion.

Kings did not want people to challenge their power.

One of the goals of the Congress of Vienna (1814-1815) was to restore Europe to the way it was before the French Revolution and Napoleonic Wars.

When Napoleon was defeated, the victorious countries met to establish a plan that could offer a relative past to Europe after so many years of conflict. So they met in Vienna, Austria in the so-called Congress of Vienna, to change things after the reorder of the Napoleonic wars, trying to reestablish some monarchies. Peace and understanding functioned relatively well until the previous years of World War 1.
