A lot of the posters have no idea how long the process to become a Republic is...IMHO, I would wager it would take teams of lawyers at least a decade and a half just to properly segregate and value the public and private assets of the royal family and provide an agreed upon valuation as to any private assets that are of national interest.
Compulsory purchase will protect the RF from the government seizing assets without appropriate compensation because as citizens they would have the same protections from the State as any other citizen. And anyone thinking otherwise should take a long hard look at asset-based lending and understand the nightmare that would ensue as the value of the pound would be completely eroded if governments can seize assets from citizens without compensation...you'd be lucky if £1 was worth 1 US cent.
And everyone representing the taxpayers in the process needs to be paid. The lawyers, valuation consultants, accountants, auditors, preservation specialists, antique appraisal specialists, carbon dating specialists, etc. And parliamentary time is a zero-sum game where time spent unravelling the monarchy is time not spent on critical national issues such as Infrastructure, Health, Defense, Education, etc.
The grass is not always greener on the Republic side of things. France has had 3 legislative elections since 2017 and Germany has a recently elected, newly formed coalition government. Neither government is expected to survive to the end of the year, so taxpayers keep paying for more and more elections. French taxpayers pay for the upkeep of Élysée Palace, just like German taxpayers pay for the upkeep Bellevue Palace and UK taxpayers would still pay for the upkeep of Buckingham Palace as a government building...which if people read the article is the reason for the increased spending as this is the first major refurbishment since the 1950s!
Finally, for those who think, well we had one Restoration so we can go for a second Restoration if the "new Ollies aren't jolly"...good luck getting any of the RF back to be abused by the public and the media!
