Why does Islam not support the spiritual piety by abandoning the traditional world life(monasticism)?

Verse 26-27 of Chapter 57:

We sent Noah and Abraham and placed in the progeny of them both the Prophethood and the Book. Then some of their descendants adopted guidance but many became transgressors. After them We sent Our Messengers, one after the other and followed them with Jesus son of Mary and gave him the Gospel, and We put in the hearts of those who followed him, compassion and mercy, but monasticism they themselves invented. We did not prescribe it for them. They invented it themselves in order to seek Allah's good will. But then they did not observe it as it should have been observed. We gave those of them who had believed their rewards, but most of them are transgressors.
