I feel like the disillusionment you bring up precedes the abstract work and is not consequent of it. You might find you would still be disillusioned even with more grounded work all the same. Additionally, all of the engineering, logistics, sales, sourcing, software design of equipment to make a functional kitchen, or build a machine to operate, or get a shovel in your hands, and build the roads so you can drive to do those things still needs to be done.
