Keepeth My Daughter a PURE Virgin OR ELSE Fer-boy

Okay this is how this whole discussion of marriage in Act IV would have happened in modern times:

PROSPERO: So my daughter? Yeah, she's a virgin--mainly because we've been stuck on this island since she was 3-years-old. But also, I'm really controlling and focused on the idea of keeping her "pure" or whatever that means, so can you like...just not hook up? Until you're married? You know like us good ol' Christian and law-abiding folks do?
FERDINAND: I don't know man, er--I mean sir...I love her and so I really like, respect her, and if she wants to hook up then...I'm not gonna argue with that to be honest.
MIRANDA: Life! Love! So many possibilities I had never even dreamed of! Let me just live life to the fullest and experience everything!
PROSPERO: MIRANDA, NO! PATIENCE IS A VIRTUE! I SWEAR TO GOD IF YOU TOUCH HER VIRGINAL KNOT--
FERDINAND: Hey man...you need to cool it. She isn't your property, and you need to stop acting like this marriage is you passing your property onto me. I love her, and she loves me, and that's totally cool, so we're just gonna ride that totally tubular wave.
PROSPERO: She IS my property and everything needs to go HOW! I! AM! PICTURING! IT! It's my way or the highway so you just need to deal with it or I'll cause another storm and kill your surviving family and friends!
MIRANDA: Wait...what did you say Dad?
PROSPERO: What? Nothing? *casts an illusion spell to make them forget the last ten seconds* What I mean to say is...I care about you, and don't you want to be the best wife you can be to him? To a prince?
MIRANDA: How does what we do in the bedroom make any sort of difference though, father? Won't I still be the person that I am? The person that he fell in love with? How will I be any sort of changed?
PROSPERO: Your...body will be different. And that's what's not okay. You just like...*need* to be a virgin okay?
FERDINAND: *whispers to Miranda* If you had been outside of the island...these are really dated conceptions your father is speaking of. Women used to be seen as property, and that's *totally* not how it is anymore. You can do whatever you want with your body! We'll discuss this alone later tonight.
PROSPERO: I HEARD that--what? Oh. I need to go take care of something. Don't come within two feet of each other until I get back! *runs away*

Prospero Talking to the Audience??

After reading the summary for the epilogue of scene 5, I realized that Prospero was talking directly to the audience. My question is why? Why does he talk to the audience and ask them to applaud him after the play is over, why not just go ahead and end the play there?

Couldn't he just kill them?

If Prospero has all of Ariel's powers at his disposal, why are the tasks he asks Ariel to carry out for him so small? Why put people to sleep to eavesdrop on your enemies' conversation, play mysterious music here and there, mimic voices to cause drama in a group, and threaten enemies in the form of a harpy? Why is that the lead-up to the perfect revenge plan? Wouldn't it be easier for Prospero to get his vengeance simply by killing his brother? Or maybe just stealing the boat and stranding him on the island? But, no. That would make too much sense.

Colonization?

Prospero's Values

At some point in the reading, I came to the realization that Prospero is one of, if not the first fictional characters that we've learned about that actually has some sort of support system: Family. This being said, I think because Prospero has family it changes what he values and how he uses his "magic". Family is such an important value to hold, it means that a persons not alone, they have someone to rely on and relate to. I think family can completely change your objective, you have someone looking up to you and even relying on you too. Prospero having better values than some of the the main characters we have read about before makes him a little more relatable and realistic to me. He doesn't seem like some far out, power maniac, he seems like a person.
