Hole Digging for Carbon Dioxide

In the old Army (say World War II vintage), we had a good job
creation technique. Dig a hole and then fill it in.
Is a lot of the government stuff we're doing now in the same
category?
For example, why not spend multibillion of dollars installing
processes and equipment to sequester carbon dioxide (digging a
hole). We then later may say, "Hey! There is new data. We need
more carbon dioxide in the atmosphere". We then dismantle all of
the carbon dioxide sequestering system, because it's in the way
(filling in the hole).
