Cause nine times out of ten whatever's being fought over needs to be kept at least partially functional. Hive worlds need hab blocks, agriworlds need farmland, mining worlds need equipment, and forge worlds need manufactorums. The only time the imperium actually destroys a planet is when it is already lost, such as deep rooted chaos corruption, heavy tyranid infestation, or recently realized tomb-world status.
