I think with regards to growing in coco or not:
- It's not more difficult than soil, IF you are methodical enough to properly pH the water and measure the nutrients correctly.
- Watering is actually easier, because overwatering is barely an issue, but of course it has to be done more often, unless some kind of automatic watering is in place.
- It's definitely not more expensive than soil. Coco can even be reused multiple times.
- Pests are much less of an issue.
Reading questions around here I don't get the impression that soil makes it easy, at all. Certainly not easier than coco.
If setting up a simple gravity-fed drip irrigation or a wick system is too hard, then probably so will be pH-balancing the water. Maybe get a different hobby?
In my experience learning how to grow is not more difficult than learning how to bake a cake or follow some non-trivial cooking recipe. All of which require some discipline; you need to water plants, and you cannot let the cake burn by setting the oven too high and then forget about it for several hours.
