If your installed system is that mucked-up from mucking around with it, then I can agree that a fresh Garuda installation may be warranted. But the fact that Arch is a rolling release has no bearing on how your personal system got personally mucked-up, but here's a clue: Arch didn't do it.
Please don't take that personally; I have a bugaboo about placing blame where it properly belongs. Blaming big daddy Arch is popular but misguided. What "they" say about it is often incorrect. Don't be influenced by that crowd.
P. S. Love that nick.
