I didn't argue that the user base can't increase. Only that those who are "likely to be both willing and able to sink heavy moolah into BTC" already know about it. Nothing more.
So a pretty narrow argument then.
You agree the user base can rise by an order of magnitude easily from here. And you realise that currently the vast majority of investors (from a multi trillion dollar capital pool) do not have a tax efficient vehicle to obtain regulated exposure to btc yet.
Not sure why you are arguing that bitcoin is even remotely close to being saturated with investment demand, unless you are badly trolling, which you are.
I'm not arguing that the Bitcoin market is saturated. No more so than the Beanie Babies market is saturated. Both can grow by several orders of magnitude.
Re. "[lacking]regulated exposure to btc": Sure. Exactly what makes "investing" in BTC a gamble. Lack of regulations/legal recourse when the counterparty decides to own you.
Governments, banks, and payment processors all have an active interest in providing support/legal framework/jackbooted thugs for addressing fiat fraud. All these bodies benefit from reducing the risks of transacting in fiat.
To be fair, Bitcoin has maths and sciences to protect you from the likes of Bitconica, WeEx, Gox, NeoBee etc., etc.
