There isn't enough liquidity in the Bitcoin asset to accomodate the $200 trillion net worth. Just $10 billion (actually much less because a market is greater than the actual cash invested in the asset during an all time high price, since not everyone paid the highest price) caused Bitcoin to have a severe bubble and crash in 2013.

The only way the liquidity can scale orders-of-magnitude faster is decentralized financial derivatives:

Non-technical n00bs don't understand the technical meaning of "scale", so n00bs please don't waste my time with your nonsense.
