I find the tokenization of a Ferrari to be really painful.

There are too many problems with it.
One, its a real thing, it requires storage and maintenance.
Two, it is a thing that is meant to be driven. When driven, its value can be reduced to zero in an instant.

Keeping such as an investment is an abomination to car lovers.
Why should we have built such an excellent car... that will never be a car?
We should have just made a digital picture of a car for all its worth.

There is a problem with "investment" that is the basis of what you fear.
There is no such thing as investment.

Our stock and bond market are a giant ponzi scheme.
Where the newest guy pays more for the same thing as the last.

There isn't any more value in the stock market then there was 10 years ago, many would say that there is lots less. So, why is it "worth" more today?

The price to earnings ratio are such that you will never get your money's worth in your lifetime.

Anyway, the point i am trying to get to is that there is no investment without keeping people out of the market. If everyone was in the market than the value of the whatever would be the amount of production that person's labor could produce. Or pretty much 1:1.

This entire thing of getting a percentage return is only available to a system of inflating currency.

So, in the end, what cryptos will show us is that there is no ROI where you can park money.
ROI only exists where you are creating something new and valuable. And people won't be selling that for mere dollars anymore.
