Russia’s war runs on oil, so less exports mean more oil for the war. Money is of course also important, but I really want the oil wells destroyed so that Russia can’t fuel their war machine (less oil pumped is also good for the earth in general). Second best is destroy all the refineries so that they can only export what oil they pump as crude - but then we somehow need to stop fuel imports.
With a good finish OSB can look nice. Enough epoxy to make the surface smooth for example will let the grain show through while not having splinters. Look at the interesting patterns you can put on epoxy countertops. Consider putting fiberglass in the epoxy as well for something stronger than plywood.
Personally I lean to more solid wood. But then I’d build my cabinets with just hand tools if I had time.
