I don't know what the frontier is on TPS and value in financial systems. Does HFT or market-making really add that much value compared to direct capital investment and the trading frequency of an LTSE Long Term Stock Exchange? High tx fees (which are simply burnt) disincentive HFT, which may also be a waste of electricity like PoW, in terms of allocation. Low tx fees increase the likelihood of arbitrage that reduces the spread between prices (on multiple exchanges) and then what effect on volatility and real value? But those are market dynamics, not general high-TPS system dynamics.

You can see the trend better in the world of instant payments, if you look to India's UPI or Brazil's PIX, how they've taken over from cash and are disrupting credit card transactions, with this starting to spread to Europe and the US: https://www.npci.org.in/what-we-do/upi/product-statistics https://www.npci.org.in/what-we-do/upi/product-statistics However, it's not limited to fintech. For example, in some countries, energy used to be transacted once a month. Someone would come to your house or business, read your meter, and send you a bill for your energy usage. With the world moving away from coal to clean energy and solar, this is changing because the price of energy now follows the sun. So energy providers are starting to price energy, not once a month, but every 30 minutes. In other words, this 1440x increase in transactions volume enables cleaner more efficient energy pricing. You see the same trend also in content and streaming. You used to buy an album, then a song, and now you stream on Spotify and Apple. Same for movies and Netflix. The cloud is no different. Moving from colocation, to dedicated, to per-hour and then per-minute instance pricing, and now serverless. And then Uber and Airbnb have done much the same for car rentals or house rentals: take an existing business model and make it more transactional.
