No, I did not. I didn't say nor implied that. Nor is it the next "logical" step. What I said is that I want to be able to change my spec without farming for hours upon hours upon hours for randomly dropping orbs.
Other games accomplish this either through having the players pay an exorbitant in-game fee or do a fiendishly difficult questline (or both). However, in PoE, it is more cost effective timewise to restart a character due to the RNG nature of the orbs.
You don't have to rely on the RNG nature of orbs, though.
By Act 3, you can trade with one of the NPCs for almost every orb that drops (except, I think, things like Regal, Exalted, Blessed, and maybe one other).
The trade goes from Alteration, to Jeweler's, to Fusing, to Chance, to Scouring, to Regret...and then on to Alchemy. It will be absolutely possible to obtain enough without relying on them dropping that you can make significant changes to a character.
Now looking at the Dagger vs Claws? There's a few hubs of those (some near the Shadow start, some near the Ranger start), and those aren't far from each other. Should you decide you want to switch, it would take around 15-20 at most to switch from one to the other (less for the ones near the ranger, which are right next to each other). Certainly not the "Oh I want to make my character a claw based fighter today" flexibility, but still very doable with a bit of time invested.
And honestly, by the time those extra stats from the weapon specific nodes become truly important to a build, you're likely at the higher levels, where obtaining the orbs you want is easier and faster (of course, you have to juggle the need to respec versus the desire or need to work on upgrading gear at that point).
That said, the general wisdom I've seen around is that you don't want to spec into weapon specific nodes unless you intend on building a character around those weapons. It's your choice on when you want to restrict yourself to performing better with a given weapon type, and especially early on it's very unlikely you will hamper yourself by not locking your character into a weapon type right away.
Still, you can choose to do that, or not do it.
