And no I don't see Netero being able to block that either given he's stated as physically frail compared to his prime. AP isn't some kind of mana shield where you just drop more AP to cover for whatever mistakes, or the Ants with their off the scale AP reserves would never get hurt from any human-based attack and yet they clearly do take damage. It's not like you'll see someone punching you and say, "If I use 1000 AP to reinforcement my arm I can block it, but maybe I should just lose my arm and save that AP for emergency".
The whole flow of aura argument does not apply to Kurapika because Emperor Time essentially gives him more levels as opposed to more experience. We can see that the level cap concept applies to everyone in HXH. Netero didn't have some backup special status move when his regular move was doing no appaernt damage to Meryem. Hisoka basically has one combat move (the deception really can't fool an expert). In general we see that characters in HXH have a very limited moveset and it has to be restrained by the 'level cap' concept, unless Kurapika is the first person to realize "Having extra abilities = great!" in all of HXH.
Let's take Kurapika's healing ability. It certain uses Materialization + Reinforcement. To keep things simple we'll say anyone who has the same level (and level and % affinity are completely linear) can do exactly the same thing, so you need level 6 Reinforcement + level 10 Materialization to do it. How hard would it be for someone else to learn this? Well another Materilization user would need 10/0.6 = level 16.6 before he can learn the equivalent of level 6 Reinforcement, since it's 60% for level and 60% for effectiveness.
Now how hard is it to get a 'level' in HXH? When Gon and Killua were training for Reinforcement, the level 1 training requires you to break 1000 rocks with a single rock. Biscuit said that normally it'd take several weeks to even break 100 rocks. Further, Biscuit said that you should only train one type of school a day, presumably because otherwise this only dilutes the effort. We don't know how long it took Gon and Killua to complete the level 1 training, but it looks like a timeframe on the order of weeks, not days. And both are unfathomably talented compared to everyone else in HXH. It's also pretty clear that these level must be exponential in nature as Gon made literally no progress on the level 5 Emission training despite a month of training, and again this is from someone who has arguably the highest innate talent in HXH.
So 'train harder and get more levels' is simply not an option, not to mention 3 of the 4 main characters in HXH starts with unfathomably level of talent to begin with so it's not like you can outtrain these guys. Assuming no fractional levels, a normal Manipulation user would need to train to level 17 Manipulation, and then he can learn level 10 Reinforcement, and it'd be at 60% effectiveness so he can only use effectively level 6 Reinforcement at 100%.
Netero is said to hit his limit and then embraked on a decade long training to surpass it. I'd argue all that training merely increased his level by 1, and he's powerful because while every other person in HXH is an equivalent of level 10, he's level 11. Keep in mind that a powerful abilty like Judgment Chain only uses level 4 Emission, so these levels are huge in HXH.
It's because gaining levels is so hard in HXH that you're better off going for something with more tangible benefit like the ability to move/generate aura quickly. You can embark on a training camp and never even come anywhere close to hitting that mythical 'level 11'. Certainly Netero is the only human we know of that has surpassed whatever this 'limit' that Netero surpassed via training, so it is entirely possible other less talented indivdual can waste their entire life training and never even get to level 11, let alone level 17!
But again, none of this applies to Kurapika because he essentially starts with more levels. Whereas a normal Materialization user needs to be level 17 to use level 6 Reinforcement (level 10 Reinforcement * 60% effectiveness), Kurapika only needs level 10 to use level 6 Reinforcement. This allows him to master more moves than other people could have (his moveset is far more comprehensive than just about anyone in HXH) and when you've more and better special moves, you don't really need to worry about anything else.
