Wait till we get far enough in space.

The voids will prove harder than the oceans.

No, space is hard because of radiation and great distances, but a hole in the hull of the ship, for example due to a micro meteorite, can even be covered with a piece of duct tape. A hole in the hull of a submarine however is a catastrophe, if it does not directly cause the hull to implode, the water that enters has enough pressure to cut you in two.

The current "space" we go into, tends to have a tinny amount of atmosphere. (1.322×10^-11^ Pa according to some random top result on Google)
So if you want to keep inside conditions at around 1 atm for a human to stay, that's all the difference you need to keep, and a duct tape might work.

But the void I refer to, is very different.
Think:

Vaporising metals
Theoretical quantum bubble formation

Normal spacecrafts made for "space", might even have their outer surface constantly being diffused in the void.

Disclaimer: I'm not a space nerd. The above is just speculation

Sure, but doesn't the outer surface diffusing apply to the friction of water against a submarine's hull too? No clue about theoretical quantum bubbles, but it doesn't seem like anything that would affect spaceships in particular.

friction of water against a submarine’s hull

I can't say for sure, but I feel like the affect due to said friction would be much lower, considering we are managing solid-solid friction in a lot of places.
