The advantage with hollowing out Phobos is that its already hollowed out. The low weight proves this. So someone has done this already. Which is hardly surprising. A few years ago I came across information that proved the former existence of an industrial outpost on Mars. It was total proof. Convergent evidence with no argument for the contrary case. Well there was a couple of bankers, the moron Cambria, and the Imbecile Andrew Dumbell of Ozrisk ….. A blog that tries to pretend that science can be made of a ponzi-scheme ….. hypnotising themselves into not seeing what they were looking at. Then there was my babysitter of the time ….. Tillman. But none of them had an argument. Total proof on one side and no argument for the contrary.
Anyhow the reality of the electrical nature of the solar system could not have escaped the decision-makers of a civilisation who had their act together enough to set up camp with industrial gear on Mars. So that civilisation ( probably humans prior to the quarternary extinction) would clearly not miss the opportunity to turn Phobos into A Dyson-Harrop satellite already.
So there is no doubt that Phobos will be found to be hollowed out, and 100% certainty that NASA and the disinformation crew will be making sure that few people absorb this reality.
Go find out the excuses for the low weight of Phobos that comes from these drooling retards. Its an incredible eye-opener.
