"Would you purchase a boat with this much wood?"
Sure. Why not?
I must admit, I would be unlikely to own one of these particular boats, as i do not care for the type, design. But there is nothing wrong with the use of wood, fully encapsulated in epoxy and 'glass. In fact, that is an excellent material, especially for "one-off" construction. Light, strong, cheap ( in one-offs ).
As with all materials, it has a care and maintenance schedule particular to the specific materials, but the maintenance is no greater than any other type, and the care is no more difficult; just different.

The use of wood ( epoxy encapsulated wood in particular ) in boats currently has an undeserved bad reputation in boating, mostly due to the improper use of the material by boaters who do not understand the strengths and weaknesses of the material.
Epoxy is the best of the polymers, having the lowest rate of water intrusion. Wood is an excellent structural material. By combing the two you end up with a strong, stiff, lightweight composite that can rival steel. But you must preserve the integrity of the "capsule". And you must build it correctly from the get-go.
If the wood is properly saturated with resins to ensure proper adhesion, you are off to a good start. Then you must not pierce the capsule. This iw where most failures occur in those boats where the owners complain. ( ie: is is poor care/maintenance by the owner )
Done properly, this material can produce boats superior for many purposes to those made of steel, aluminum or solid FRP.
I'll take a properly made and cared for epoxy encapsulated wood boat over the other materials any day. It is that good.
You do not see much of it for two main reasons:
a) This is a very labor intensive construction method, and it is not well-suited to "production" boats.
b) Due to owner/operator mis-handling of the material, their errors have given it a bad rep ( promoted by production boat builders who want you to buy their inferior production boats )
In my opinion.
