What happens to the value proposition of Bitcoin if the world follows the example of Portugal?

Often people present Bitcoin as having an advantage over traditional banking services due to the lower transaction fees and speed. From my understanding, one of the reasons Bitcoin is better than traditional banks is that it allows for quick and low-cost transfers in a short amount of time.

However, this is already the case in Portugal with traditional banking services, and I'm having difficulty in understanding why these measures could not be adopted globally.

I'm specifically referring to a service called MBway that every bank adhered to, and that is free to use in almost every bank. Using just a phone number, you can instantly send money to someone else, with zero charges. You can send up to 700 euros at a time, up to a total of 2500 per month. All free of charge, and instant. It's also what I used in my small business. Most people pay me using the app, and neither I nor the costumer pay a cent for it. Granted that there is a limit, but still.

On top of this, I have two bank accounts on different banks where I pay zero. And I mean zero. No card fees, no maintenence costs, nothing. On one of the banks I even have 40 free instant SEPA transfers a month. So should there be any issues with MBway, I can just use this feature for free, I believe with up to 50000 euros limit.

I know that Bitcoin has a lot of other added benefits, like anonymity, decentralization, etc. But from the experience I have in Portugal, for the average consumer, adopting a system like the one we have in place seems to me like a threat on adoption.

What do you guys think? Did you know that it worked like this in Portugal?
