Morphology
The meaning 'to deliberately prevent someone from carrying out or achieving what they have planned' is directly and transparently derived from 'obstruct' (to block or impede) combined with 'someone's plans' (that person's intended actions). This is a standard verb + object composition with predictable semantics and cross-linguistic parallels, so a B1 learner who knows the constituent words will readily infer the MWE meaning.
Etymology
The verb obstruct someone's plans comes from the image of putting something in the way of a path: obstruct means to block and plans are the way a person wants to go. So, to obstruct someone's plans is like putting a barrier in their way and means 'to stop or block someone's plans on purpose'.
