To be fair, he is still doing the infrastructure build up. I think the only difference is that he has moved from the liberal agenda; but he only followed that agenda to have a shot at the EU membership. Once that became not a viable option, he obviously regressed on that.
I don't think keeping the same policies as the 2000s would have avoided the hyper-inflation spirals though it might have marginally helped. Turkey issue is that it can't move from being a poor economy (as in simple rent industries like tourism and packaging stuff) to a middle economy where they can manufacture some stuff. Istanbul is a very misleading city because it paints a different picture to the reality of the average turk once you are outside of the city bubble.
Tourism is a pretty good sector for the economy, especially because by its very nature you have to compete internationally with the rest (and best) of the world. There's no shelter behind tariffs or similar.
Tourism in Turkey is essentially one dude owning the land/establishment and 10 dudes running around serving tourists. Nothing wrong with that if that's a small part of your economy but if you have most of your people doing that, then it's definitively a mismanagement of your country talent.
