You're right-you still need to have space to work in the tank and get things in and out it. For anyone with the headroom, there are many benefits.
Check out ebay seller "insulationdepot", they also have their own website. They recycle building materials from building demolition, particularly foamboard, and have many warehouses across the US with reasonable shipping. Their inventory is low now but should build up soon, as the demolition season starts in the spring and runs through fall. Their inventory dries up in winter, but I have seen a 4x8" pallet of 3" polyiso 92" high for $250 and less when it is mostly 4x4' pieces and smaller-perfect for fitting between joists/tank supports.
