Maybe people won't need a bank in the future as they switch to DeFi services. and this has begun to be proven by the presence of many Chinese citizens when dealing with banks, they are dealing with Alipay and WeChat, at least doing this kind of financial behavior without going to the bank.
Let me guess, you think that not only there is no bank behind WeChat and AliPay but you also think that those two are decentralized? You are just fooling yourself by thinking you're not dealing with a bank, just as some people think that if they have a crypto card there is not a bank behind the payments done via the Visa and Mastercard network.
Nobody is using those defi services, there is currently no real-life application for them all they do is swap tokens all day and pray they go up in price.
Have ever used it for anything else? Ever?
Defi is something we are trying right now, trying to get our own economy in our hands and if we can achieve it, it would be world changing, if not it would be just a failed attempt.
Again, the same question, how are you going to get your own economy in your hand? And more specifically, what's this thing called
your economy?
Things can co-exist together,
A lot of people argued the opposite, bitcoin was supposed to kill PayPal but, look what's happening, it was supposed to be a banking killer yet thousands each day buy and sell coins while dealing with wire transfers, there are still people who think this defi hype will replace something when in reality there is almost no need for its existence.
you have good points regarding the actual usage of defi services. just take for example the yearn.finance, which reached their ATH just last month at about $43k (higher than what btc achieved so far!) , and now look at their current price a month after reaching that price, trading at $11k. but are you gonna ask yourself, where that price coming from? no active use case, still their platform is in forever beta stage and yet they have that price tag?
sooner or later, these defi supporters will realize that most of these defi platforms are just pure talk and theres no actual devt going on
