Thought: People with less than $500,000 worth of BTC will never touch the main blockchain.

Given that current users is 100 million and doubling ever 6 months. If we 10x to 1B (in less than 4yrs) there will still only be roughly 13% of the global population using Bitcoin. At 7 trans/sec, each of those users can make a base chain transaction roughly once every 4.5 years. It seems to me that for this to happen, the VAST majority of Bitcoin users will never interact with the base chain directly and their interactions will be limited to Lightning and other scaling solutions. What will base chain transactions look like at that point? Only million dollar moves with thousand dollar fees? Why would you need to have your BTC on the main chain? Will the majority of BTC be on the LN to provide liquidity and act as a settlement layer for a higher layer scaling solution? The devs have their work cut out for them.
