Isn't central bank digital currency just simply your bank balance in digital balance which is simply internet banking?

On investopedia, it says CBDC(central bank digital currency) will be centralised, issued and managed by central bank. If we ban cash and allow only digital transactions through internet/mobile banking, wouldn't it achieve the purpose of CBDC?

Also will it be Minable? If yes, wouldn't it mean printing your currency?

A CBDC is very different from what we have with banks, always remember that a CBDC is supposed to be like cash, but digital.

Using your debit card ou sending a wire transfer might seem "fast" but the infrastructure behind it is actually slow, transfers between banks can take more than one day before the recipient really receive what you paid him.  Cash is instantaneous.

There is also the fact that you need an account at a bank to use those services. You don't need an account to receive cash, wanna sell some thing ? Someone can give you a dollar bill and you live.

And to conclude, the current payment infrastructure is not ready for the financial innovation that came with cryptocurrencies.

The goal of a CBDC is first and foremost to be cash-like since the use of cash is dwindling it could act as a replacement. 
You don't need an account at a bank to use it, everyone with a phone can use it, your only counterparty is the Federal Reserve, like regular cash.

This way, it facilitates financial inclusion for those who can't have a bank account and it's also very resilient, during natural disasters for example, you can't necessarily have access to an ATM or use your debit card but the NFC chip on your phone works **even when your phone is off and out of battery.** If the CBDC is decentralized you could still buy things with a dead phone.

With a CBDC, things like smart contracts could be included in our paiements systems, all of the innovations that were spurred by the crypto' wave since 2008 could be translated in a currency backed by the government.

There is also the question of anonymity, there are multiple ways to make a CBDC, and a lot of those ways implies anonymity, like cash. And what's amazing about it, is that we could get anonymity and money laundering surveillance at the same time. For most it's not a big deal, but for some people, knowing that they could make purchases off the radar is nice.

A CBDC would also be safer than actual cash, cash can be counterfeited and a lot of people sadly end up with fake bills. It would take an absurd amount of effort to try and crack a CBDC basically ending the era of counterfeited cash.

And last but not least, it's way faster than our legacy systems, transfer are instantaneous even abroad.

It wouldn't be minable though, it would be like a regular dollar or euro bill provided by your central bank.
