1)Yes but you don't experience those issues until you get to 30 million blocks away from origin.
2)Although the author of this suggestion wants cubic chunks for the ability to increase the height that is not the only positive. Because of how Cubic chunks is designed it can reduce lag considerably because less than half as much data is loaded when you move around a world.
Here is a quick very incomplete summary as to why:
2.1)We now don't need filler data for every air block, all we have to do is send a tagged null value saying the chunk is empty.
2.2)We don't have to load a dozens of 16x16x256 chunks instead we only load about the same number of 16x16x16 chunks to get the same in game experience. It will reduce loaded terrane data 8 times on average.
2.3)Cubic chunks gives you the option of infinite or increased vertical you don't have to set the vertical any higher than it already is if you don't want to.
2.4) Allows for really cool things like sky biomes and crystal caves because now we have the vertical space to make it happen.
4)If you really want to understand what cubic chunks does for minecraft read the whole post at
http://www.minecraftforum.net/topic/1707097-cubic-chunks-reduced-lag-infinite-height-and-more-over-two-thousand-supportersupdated-1015/page__mode__show if your too lazy to read the post at least read the tl:dr and the Q&A at the bottom of the post before making a judgement about the system.
5)And finally Mojang could add this to Minecraft with very little work on their part and in just a couple months. The whole system has been described in detail on the thread I listed above and there are a number of very talented developers who have already built working versions of the system in Minecraft and several of which have volunteered to write it if Mojang will put it in vanilla.
If you want less lag farther view distances and more possibilities in minecraft support cubic chunks by up-voting this issue and adding this to your signature on every forum you can.
