opening bid, I have:
S: AKQ9873
H: AQ
D: xx
C: Qx
Could I ever justify opening 4 spades?
I have more than eight tricks in my own hand, with seven of them in spades. At the same time, I fear the weakness of my minor suit doubletons.

Tl;dr: No, bid 1♠.
There are many different sets of bidding conventions in bridge. In the one I learned (some further information here: http://www.rpbridge.net/3j00.htm), 4♠ is a preemptive bid that signals a very long spade suit (which you have) and several points below the regular opening strength of 12 high card points. Your hand is too strong for that (even if you play where the unprotected Qs aren't worth points), so you should bid 1♠ instead and then further tell your partner about your amazing spade suit by rebidding it at your next opportunity, probably jumping a level when you do so (e.g. 1♠ - 2♣ - 3♠).
While other conventions may differ somewhat, it is unlikely that any will tell you to open 4♠ with that hand. This is because, although your hand is quite likely to make 4♠, if your partner has any strength you might be able to make a slam instead, but if you start the bidding high then there's very little bidding space for you and your partner to figure that out.
Your hand is too strong to open four spades.
You might bid like that with AKQ9873 of spades and no other honors. That's because you will be able to take seven tricks in your own hand, but have "no defense" outside of spades. Your ace will likely take one trick against a presumed singleton, but the opponents have a small slam, if partner has nothing.If playing "strong" pre-empts, I might bid four spades with AKQ9873 of spades and Qx of clubs, but two little hearts instead of AQ, in fourth seat, but not first.
With one additional ace in your hand and two queens outside of spades, the opponents do not have a potential slam, and probably no game, since your weakness is in the minor suits. So you don't worry about partner having "nothing," because you can defeat, and probably double your opponents on your own if they tried to outbid you for a game. You have the spade suit, so they will have to bid the game at the five level.
In that case, bid "normally" with one spade, and give partner a chance to respond naturally, since you are in first seat. If you start too high, you are "preempting" partner, not the opponents. With so many extra points coming from extra trumps and "distribution," someone (partner or opponent) is going to bid. Unless this is a very weak group, you will not be passed out. (And if you are, you might want to find another group.)
One other thing: your hand is almost, but not quite good enough for a "demand" bid of two clubs, that forces partner to bid two diamonds (or higher) unless the opponents intervene. Change the queen of clubs to the ace, or a small diamond into the king, and I would bid two clubs. That is a "lower" bid that leaves more room for partner's response than four spades. Depending on what partner has (and bids), you would likely either play the hand, or double the opponents for a profit if you were strong enough to bid two clubs.
That particular hand should certainly be opened 1♠. 4♠ is a preempt, as has been noted; it's often a preempt-to-make, meaning a hand that you think has a decent shot at actually making 4♠, but only because of the distribution. However, if you'd make that bid with this hand, how will your partner know whether it's appropriate to bid on to slam?
There is a good convention for handling "strong and long" hands like this, though; NAMYATS. I play that it requires eight cards in the suit, but some play it with seven, and splits the bidding this way:
The same applies for hearts (with clubs being the strong bid). This allows you to tell your partner the difference between a "good" 4♠ and a "poor" one, and gives your partner some very powerful responses.
