1. Because I can. Which is a very good answer, but doesn't quite reduce the crazy factor in their eyes.
2. Because not everyone has the money and space for a floor loom or even a table loom. My Ashford RH 32" fully kitted up with pairs of every size heddle and even a stand costs considerably less than even a 15" 4 harness table loom. It can hang on a wall when not in use, even in use it takes less than a square yard of floor space.
3. Because my simpler loom has a lot fewer parts to break or need maintenance.
4. Because my largest RH loom weighs a lot less and is more portable than even a small table loom. I have friends who can no longer carry a table loom but they can still manage a smaller RH. I can carry my 32" RH with 2 fingers, my Cricket 10" fits in a shopping bag and I can lift that with 1 finger.
5. Because the RH is better at some things than floor or table looms. If I'm careful, I generally have less than 15" of loom waste; I'm a handspinner, remember, I can't stand loom waste. The RH works at lower tensions, which makes it easier on some yarns. And I can weave Summer and Winter tapestries which would require more shafts and many more treadles than any floor loom has. Pick up sticks are a lot easier to use on my loom because it's easier to reach where they need to go.
6. Because the RH has required that I begin to really understand the interlacement of threads. The fell line is right under my nose, I really can't miss what's going on. And I have to handle the heddles and the sticks in such a way that I am aware which threads are up and which are down. Trying to figure out how to make things happen on my loom means I am learning a lot more about structure a lot faster than I would if I could simply follow a draft.
Yes, a floor loom would be faster for many of the things I'm contemplating. But I am not trying to clothe my family nor make a living production weaving. I am weaving because I enjoy the process. And I am enjoying the challenge of figuring out how to make it work. Even when it doesn't quite:
