My first job was in a machine shop in that experience I learned that a machinist will create a true surface or start from a previously trued surface. In woodworking you are creating a trued surface and progressing from there, each tool provides a range of capabilities and will either true a surface or work off a trued surface (or both).
An experienced woodworker is likely to have an in-depth understanding of this and how he can work with it, check it for flatness and so on, where an amateur who is in the beginnings of this hobby may not even be able to discern a truly flat surface from one that is not quite flat, so he is more likely to feel he needs to reach for a tool more capable of providing a trued surface than one that relies on his ability to create one. An experienced woodworker is also likely to have a very well equipped shop, even though often times he may not need to rely on anything other than marking tools and a set of chisels, the amateur however may feel disadvantaged because he has neither the breadth or knowledge nor the tool chest of someone more experienced. His first steps may be to buy the tools, since it's half of the process.
There is no need to fault someone for wanting to equip their shop with the tools they may find themselves to need, it's no more ill advised than the expert who continues to collect tools with a diminishing set of tasks that each tool can accomplish. Their reasoning is not that different, they both want to accomplish something with less struggle than previously required.
Also, there is a side benefit to the amateur's interest in all of this; I'd be willing to bet that companies like LN and LV are selling much more often to amateurs than experienced professionals, driving their ability to further provide the engineering and capital required to issue more and more redesigns of vintage tools. The rare tools bought up by experts only exist because LN and LV sell a lot of jack planes and panel saws.
Bumbling forward into the unknown.
