If the monarchy falls, so does the aristocracy, the ludicrous British Empire honours system etc. It won’t make a financial difference but, over time, it will make a big difference to the social/class system, the law and the constitution.It’s what you replace the monarchy with a “republic” ? technically nothing changes it won’t affect me or mine in any way.
I would still be taxed for the upkeep of the president and his estate, unless it’s proposed to re-distribute the Crown estate wealth and give us all a handout, the king gets to keep all his personal wealth and property “nothing changes” there is no point in agitating for change.
Change makes no difference to me or mine I could probably watch all the castles and houses go into private hands or fall into disrepair as so many do and I get to vote for a president in an election which has to be paid for out of public money I’m happy with the way it is.
I know how as a country we work surely that’s the point the case for a republic is long gone and in the past, when the majority of people were poor with no future.
As things stand one wonders how it would come about since our constitution forbids parliament from discussing it. (Bit of a clue there. Don’t forget the sovereign is immune, he cannot be arraigned in his own courts.)
