I have read an article 'Super-rich may quit London homes under new anti-corruption rules'

Billionares who have been buying property will like to keep their identity hidden, however a new public register in the UK will mean identities of the wealthy will become public.

Some people like their privacy, it does not mean anything illegal is going on due to keeping their name private. Some people do not want the limelight and others want the safety and security of their family.

In terms on Human rights, why is it important for wealthy people to be able to keep their identities hidden.

The only 'human rights' reason is to keep kidnappers less likely to find the super rich.
The the US, all real estate property ownership and sales transactions are public information.
The way to hide ownership is to form a real estate trust.

Oh wait - all your other questions are homework. I knew this one might be too, but you fooled me with 'I read an article..'
Why do you want other people to do your work?
What's the POINT of not doing it yourself?
