Cut healthy roots back?

[Bud]

I purchased seaweed mix to produce healthy robust roots for my orchids...now why would I cut the healthy roots???!! I believe the more healthy roots I got the better blooms the plant will produce.
I would rather adjust my pot size deeper, longer or wider than cut off the roots to fit a pot.
Aesthetics are for the florists display in a shop = we are orchid growers....I care for the welfare of the plant. Leave those healthy roots alone!
