IYDHITYDOI is becoming a clear fact to people who had never considered it as a problem.

Bankers and finance people use the term 'counterparty risk' which is a complicated way of saying that its possible someone will not deliver on their contract obligation (which in other words is a promise to deliver a good, or service, or money at a specific date and time). 

It matters not whether they wish to deliver but cannot because of circumstances such as a change in law or other reasons.

Or if they simply choose not to deliver on the contract. In either case, your plans go unfulfilled.

If it happens that your plan was wealth and security by ownership of important assets that are now not delivered, then the consequences are formidable.

The only responsible approach other than physically holding something yourself is attaching your name to the asset in a way that cannot be reversed.
