Couldn't agree more with you, mate. Sooner or later, governments will impose fierce regulations within the "De-Fi" industry. After all, they want a piece of the pie of crypto's revolution. Since decentralized finance provides freedom to everyday people, it goes against what has been established in the first place. The same way governments have successfully regulated ICOs, they same way they'll be able to regulate the "De-Fi" industry. Governments could simply hold "De-Fi" platform developers accountable for their actions. They could require such developers to force compliance of KYC/AML regulations among users of the platform, effectively bringing traditional banking to "De-Fi". Since "De-Fi" is not as decentralized as one would thought it would be, it's easy enough for governments to take action against it.
Ultimately, it's all about "survival of the fittest" than anything else. Decentralization needs to be put above all else, in order to render governments' efforts worthless. Otherwise, the so called "De-Fi" industry will see its demise in the future like it happened with the ICO boom back in 2017. Time will tell us what lies ahead with this rapidly-growing industry in the crypto/Blockchain space. Just my opinion
