Seedling persimmon drives a deep taproot, which is why it shrugs off drought and hard clay and why it is notoriously difficult to transplant at any size. The bigger practical issue is lateral root suckering — mature trees push shoots up through lawn and fence lines well away from the trunk, and mowing them off only keeps them coming.
Usually 30 to 50 ft tall with a 20 to 35 ft spread in the open, occasionally larger on good bottomland — squarely a low-cost, climbable removal with no crane. It takes roughly a decade to begin fruiting, so a heavy-fruiting nuisance tree is well established before anyone calls, and typical landscape lifespan runs in decades rather than centuries.
