I also really have to say, that every single catholic state in life is supposed to be conducive to contemplation.
Ok, but you're missing the point that Contemplative orders have lives that go far beyond being 'conducive to' contemplation. Their lives are contemplation itself.
Examples as to why these orders are important:
- Moses prayed alone on Mt Sinai for the Jєωιѕн race. He was an intercessor of sorts.
- Christ often withdrew, in solitude, to pray. Specifically for 40 days and 40 nights - which is the example we have for Lent.
- Our Lady, mother of the Church, lived her whole life in contemplation.
Here is a short article on the value of contemplatives to the Church:

“For God alone my soul waits in silence,” declares the Psalmist, (Psalm 62:1).
The desert father Ammonas, a disciple of Saint Anthony, writes,
“I have shown you the power of silence, how thoroughly it heals and how fully pleasing it is to God. Know that it is by silence that the saints grew, that it was because of silence that the power of God dwelt in them, because of silence that the mysteries of God were known to them.” It is this recreating silence to which we are called in contemplative prayer.
