Except you do have the problem, even if you're not aware of it!Waiting for errata to be incorporated in printed books is hardly the unreasonable or unwise choice you're trying to paint it as (after all, I'm paying money for these things). Besides, you've missed an option — it's not a question of making due with a crippled product or going without. I can choose to purchase and support other products that do incorporate errata or that don't need much of it to begin with (which is what I've done). I haven't been without. I've been playing other games. In other words: the problem that you mention? I don't have it.
Providing errata is an ongoing process. You'll never get a version of the books that is 'final', i.e. free of anything that might still require errata.
It's like saying "I'll buy this software product once it's free of bugs."
Since software will never be free of bugs (and even if it was, it would be impossible to prove it!), you'll end up never buying the software product.
You're saying "But there are software companies providing service backs for their software". Sure, but that doesn't mean that the software won't require additional service packs in the future.
And all of this is even less practicable for print media. Even if they did a new print run including errata after every round of errata who'd buy the same books again and again? This way lies madness.
