It's literally an inconvenience OP. Artificial difficulty at its core. It's also a really bad idea because if you catch something you really wanted or really like, you need to be able to save immediately so your progress isn't invalidated.
If you wanted to make the game harder, make Pokemon Center trips a 24 or 8 hour thing. Mind you, that's also a stupid idea but it ties into your thing about using Centers.
Really, all you need to do to fix Pokemon difficulty is change the boss battles like Gym Leader, Rival, and Team fights. Scaling, or at least decent levels is a good start. Including more Double Battles? Even better. Then you'd work on the trainers on the way down if you felt like it, but assuming this is being developed by Game Freak you can forget that.
