I'm not sure if satoshi makes bitcoin as an alternative payment system, or with the intention to create the best and most used payment system, but this second option is impossible by the bitcoin nature and i will explain why.
if you are looking for something perfect without any downsides and 0 problems then don't look for it in this universe. what you are seeking is not found anywhere but in an alternate universe!
what we have is imperfect systems that we try to turn into a better system as best as we are capable of. sometimes you have to give up some things to gain some others. if you centralized things you can have the same TPS and even more than Mastercard's. but when you want decentralization you have to think about preserving that as best as you can when it comes to on-chain transactions. then we have other solutions for TPS such as Lightning Network which will give you that TPS that you so hope for.
