If 96% of the known universe comprises, Dark Matter (and Dark Energy), why can't we tap the energy

to feed an energy starved world?

Do you know how much "energy" is stored in the dirt under your feet? How come we can't "tap that energy"? Please look up the thermodynamic terms "work" and "free energy" (also called "Gibbs energy"). Then come back and see if you can address your question yourself.
Isn't Dark Matter still theoretical? As in we haven't captured any of it yet to prove it exists?
No-one has disproved the theory yet. All we have are theories.

Energy is a great word...It is indeed 'stuff' of work - stuff we use a lot of.

Why can't we tap cosmic rays or gamma rays for energy consumption for the starved world? There's surely more 'other' EM radiation than there is visible and near-visible light -- which we harvest for solar heat and electric energy -- we simply can't tap into those energies because its simply not efficient/possible with our technology.

...

Just because it's there, that is, we are pretty sure its there, but we don't even know what it IS yet...means we can't use it yet. The laws of conservation still apply.

The ocean covers 75%~ of of the earth's surface...yet we can't drink it, for the simple reason that the 'water' is contaminated with salts and minerals. There's more water there than we could think what to do with it, but it's usually useless without expensive processing.

Lots of reasons:
1) Its not 100% certain dark matter and dark energy actually exist.
2) Assuming they do exist, we haven't yet found where it is.
3) We don't know if it exists in clusters or is uniformly dispersed throughout the universe or in some other form we don't yet understand.
4) If we found it, we don't know how or if we could develop the technology to use it.
5) If we found a way to use it, it may be so far away as to make it inaccessible.
6) If we could access it, the cost to do could be prohibitive.
7) We just don't know enough about dark matter and dark energy to do much more than theorize about its existence.
