Well, I mean, technically, with a powerful enough laser, you don't need to precisely aim it. You can use the same technique radars use and do 'sweeps', with the lasers going from right to left or up and down, or perhaps having multiple layers doing the same thing. But, as mentioned, you will still have some holes in the 'fishnet' even with this method. The best strategy is a layered defence. Kinetic protection is the most sound choice when it comes to singular impacts, but overtime it's going to fail due to multiple impacts and radiation exposure. Especially if you go for the traditional 'armor' ideea (liquid metal armour, while more Sci-Fi, at least prevents the forming of cracks).
