You can do more if you have a lot more RAM. Otherwise you really are that restricted.
In the country I live in, there is no comparable Chromebook spec-wise on par with the Neo at a similar price point. You're basically stuck with 4GB RAM.
Justifying having 8gb as a good amount, while downplaying 4gb as not enough is pretty hilarious. Chromebooks run fine with 4gb of ram, especially if you install linux and use zram+swap.
You can get a regular laptop and have even more ram with Linux. Not sure why you are stuck on the Chromebook.
