The need for a small, inexpensive hoe is best explained by the convenience factor.
Yes, I can run down to the rental place and maybe 90 minutes or so later, come back home with a track-hoe or a TLB that could dig my whole basement in a day or plant a tree in ten seconds.
The hassle is that I have to have a truck and trailer (or rent one or more of those as well), or pay for delivery. Delivery adds even more delay.
By the time the equipment was on my lot, I would instead have already decided, heck it will only take half an hour to dig this hole with a shovel, and the work would already be done.
Also, once I paid the $250 or $300 daily charge, I would be tempted to save up a bunch of little projects to do with it. That would add immense complexity to my honey-do-list scheduling, or would be a great procastination excuse.
Net answer is that I always end up using a shovel or improvising with the FEL, or some combination.
If I had a small, quick-to-attach backhoe sitting on hot-standby, I would just go connect it up, dig what I had to dig, and be done before the rental machine could even arrive.
So the value is convenience.
