To be fair, fettling an old plane to be usable is likely because of the usual suspects of the sole needing a little work, the frog needing reseating or handles needing a repair, etc. Whilst resharpening a blade is probably also on that list, most people (the OP included) will likely accept that using a ready-to-go plane requires sharpening as part of the cost of ownership anyhow - they just expect to make the other parts function in line with it.
Each to their own and what budgets they are working too, me , I'm tight old and poor !
