I also have the same thought here. But I think we need to look much deeper on the application of DeFi before jumping into conclusion. What we saw is just the outer layer of the currently functioning DeFI system but I think there is more than just loans and selling tokens. AS far as I know DeFi aims to be an alternative to the global finance system. We can learn more about DeFi on this article titled:
Decentralized Finance: An Emerging Alternative to the Global Financial SystemHere is the quoted part of that article:
The Potential Impact of Decentralized Finance
Here are five ways that decentralized finance will have an impact on the world:
1. Wider Global Access to Financial Services
With decentralized finance, anyone with an internet connection and a smartphone could access financial services. There are a variety of barriers that prevent access in the current system:
Status: Lack of citizenship, documentation, credentials, etc.
Wealth: High entry-level funds required to access financial services
Location: Vast distance from functioning economies and financial service providers
In a decentralized financial system, a top trader at a financial firm would have the same level of access as a farmer in a remote region of India.
2. Affordable Cross-Border Payments
Decentralized finance removes costly intermediaries to make remittance services more affordable for the global population.
In the current system, it’s prohibitively expensive for people to send money across borders: the average global remittance fee is 7%. Through decentralized financial services, remittance fees could be below 3%.
3. Improved Privacy and Security
In decentralized finance, users have custody of their wealth and can transact securely without validation from a central party. Meanwhile, in the current system, custodial institutions put people’s wealth and information at risk if they fail to secure it.
4. Censorship-Resistant Transactions
In a decentralized financial system, transactions are immutable and blockchains can’t be shut off by central institutions like governments, central banks, or big corporations.
In places with poor governance and authoritarianism, users can divest to the decentralized financial system to protect their wealth. For example, Venezuelans are already adopting Bitcoin to protect their wealth from government manipulation and hyperinflation.
5. Simple Use
Plug and play apps will allow people to intuitively use decentralized financial services without the complexity of the centralized system.
With a decentralized system, a woman in the Philippines could receive a loan from the U.S., invest in a business in Colombia, and then pay off her debt and purchase a home – all through interoperable apps.
The Potential Blue Sky
Unless governments and central banks suddenly cease to exist, it’s difficult to imagine a world where decentralized finance completely replaces their centralized counterparts.
But what if they can co-exist?
Public blockchains can interact with the traditional financial system to create a new hybrid model:
Users could conduct economic activity on public blockchains and exchange their new wealth into the centralized system.
Users could hedge against systemic risk by diversifying their wealth holdings in both the central and decentralized system.
Like the internet with knowledge, decentralized finance could help democratize the financial system.
