I disagree,
the monarchy have read the lay of the land and are now engaged in a massive PR campaign to preserve their power
why do you think that there is some much media related to their charity work etc
in addition the royal family support government international efforts and as such have tact support of the British government
to remove them from their throne so to speak would require a massive public movement and some massive government action that ultimately would end up in courts if the royal family resist
you need to remember that Her royal highness is the ultimate power in all commonwealth land and can do whatever she wants.
Notwithstanding that the royal family in its entirety has seeded family in all levels of power and have many powerful followers who will fight to support them. This is one of the reasons they engage in military forces to extend their power to the military as well.
Look at the Invictus game publicity in last 10 years, that is designed to shore up support for the royal family in the military
Make no mistake, Lizzy is a good operator and her family has fallen into place well, they will not be going anywhere anytime soon
