It takes 10,000 people to contribute $500 each to start a bank that provides cancel-free banking services.
It takes $20 a per person month and 24 months to for each person accumulate $500 investment – ie: buy a share of stock.
It takes a small number of individuals to create an irrevocable trust that then owns that bank.
That trust can be created such that all assets contributed to the trust prior to marriage cannot be considered in divorce.
Some states include Domestic Asset Protection Trusts specifically insulating assets from divorce proceedings.
