Would you use this giant remote miner?

[Nocturnal]

I like to have as much of my resource production as I can come from asteroids - in the early-mid game I can have half my minerals coming in from remote miners and in the late game, about a third to a quarter. That way I can have all my planet real-estate devoted to research (and later, intelligence) as it should be.

I've found of course that since you can only have one ship mining a location each turn, and you have to pay upkeep on your ships, the bigger your mining ship is, the better - because you can cram more mining modules on it. You can't do this in limited resource games, because the profit you make is pathetic. Except for mining sattelites which don't require upkeep and can be tossed around at will (though I tend to mine moons with those before I colonize them.)
So anyway I took it a bit too far and designed this monstrosity Last night:

Starbase size
Master computer, 19 remote mineral mining modules, 5 remote radioactives extracting modules. And a massive lightning ray for decoration.

I called it a "resource raper" because it sucks the astroid field dry of all its resources. I haven't built one yet but it was carefully designed to cost no more than 40,000 minerals, so that a mobile construction ship can build it in exactly two whole years (I always assume maximum tech level, but you should see the way I play - everyone else's research in the "comparisons" looks flatlined and mine is a hyperbola.)
A quantum reactor drives the price up. You could use 17 miners and 7 extractors if you wanted to include a reactor. Or 21 miners and 3 extractors and let it take another turn... or another combination with a non-organic weapon.

Once built, it's supposed to give a profit of 5,200 minerals after deducting upkeep (that looks awfully small to me, maybe I got the upkeep wrong?) at 100%, and 20,400 at 200% which is the average mining-ship-worthy asteroid field. Plus several thousand radioactives which I was short of when I designed it.

I've already selected a tiny asteroid belt with over 250% minerals and radioactives to build mine on.

Self-destruct device not included; if you need to get rid of it you can just bring back the construction ship to scrap or mothball it when it picks the asteroid field clean. This is a very expensive piece of immobile hardware and needs to be heavily guarded with defense satellites and perhaps a minefield. You could have one satellite fleeted with it, with a quantum reactor (and ecm, cloaking device, scattering armor and combat sensor to support its stack) if you want the "resource raper" to be able to fire its weapon. Otherwise it doesn't need supplies.

So, should I be straightjacketed and tossed into a padded room?
