It adds a really interesting dynamic to US markets. Imagine being able to trade while something is going on in Russia or the Middle East that will shake the markets. Some people would be able to get in or out of companies and others will be left holding the bag.

It said this would be to get around brokerages but I think that at least initally you are going to see it be brokerages that offer this. Robinhood is working on its own chain and big banks like Chase and others are operating private blockchains as well.

I like the idea of being able to trade 24/7 because some days I have missed out big time due to work but this would fix that to an extent. However, its a double edged blade and like you pointed out I dont see ETH or BTC being able to deal with not only the volume but the security needed to pull this off on a large scale.
