Captain Kidd had no need to bury his loot when many bankers would launder it for him!

With my theory I believe “Pirates” did not play a part in the building of the Money Pit at Oak Island.
Pirates had little need to build a private bank such as Oak Island when there were more than enough Banks, Financial Houses and Merchants living in New York during this time period to accommodate them.
Pirates such as Every, Morgan, Tew and the famous Captain Kidd bribed New York’s governors for protection and used these Financial Houses to launder their treasure. Captain Every was so prolific at this that he was one of the few pirates to retire back to an estate in England with benefits.
Many of the men we call pirates today were legal privateers acting with the full blessings of England.
“The enemy of my enemy is my friend”
It was only if they attacked British ships or after England signed peace treaties with their enemies were these privateers labeled again as pirates.
During the Golden Age of Piracy many of these famous pirates chose to live in New York while Edward Hyde, 3rd Earl of Clarendon was appointed as colonial governor (1701 – 1708).
Governor Hyde’s flamboyant manner of dressing was only surpassed by his reputation as the worst corrupt governor Britain ever appointed to an American colony.
Captain Kidd lived in a mansion in New York and was also involved with the construction of Trinity Church.
It was only later when England proceeded to rid their colonies of this corruption and pirating that many moved on.
England encouraged loyalist merchants and privateers to move to Nova Scotia as part of their reaction against the growing revolution in the American colonies and these colonies’ willing acceptance to trade with France and Spain against British embargos.
Many British privateers operating out of Lunenburg Nova Scotia attacked these ships and used Halifax merchants similar to those operating in New York to exchange their booty with.
