It should be mandatory

Uninvite the bride.

That was my first thought too. Uninviting the groom also works.
Oh, you can un-invite one of the in-laws for some amazing chaos too.
Uninvite the priest, I'm running this thing now
You usually invite guests to the wedding, so I'd assume bride and groom would be safe under this logic.
The parents however....

If two people uninvite each other, it's gonna cause a paradox, and the whole wedding will overflow the stack

That's how you get the $NaN glitch in your bank account, but also for some reason Keanu Reeves is the officiant while holding akimbo pistols, and everyone's outfit includes a green sweater
How would removing both cause a paradox? Removing a guest doesn't remove their Plus One, so why should removing the guest remove their Minus One?
- People who aren't guests shouldn't be able to affect the guest list, so removing a guest would remove their plus/minus one
so a kind of stack overflow?

~~un-invite the bride~~

is the bride a guest ? i guest not.

If a person gets minus'd, does that apply to her plus one? Or can the plus one attend without her?

I'll be choosing myself as the minus one, I'd love to come but rules are rules, have a lovely evening.

Can I uninvite the whole wedding and save $25,000? No, it's expected of me to spend that money.

Eloping was one of the best decisions my wife and I ever made. We still spent a bunch, but it was for the two week vacation that went along with the elopement instead of 3-4x that for a single day.
- This is what we plan to do. Makes no sense to throw all that money away for a silly ceremony where you're bound by what everyone else expects of you. We'd rather do something special for ourselves.
Just uninvite the bride.
If it's expected, you have a circle of friends that do not really align with your idea of a good life. Sounds harsh, but please, I've been to fun weddings that were had at maybe 3k€ and nobody left hungry or thirsty and the close family guests from far away were even booked rooms nearby.
- I won't say that's impossible but claims like that need a year, country, and count of guests.

Okay but a minus one can be counter acted by a plus one right?

Y es, un the sense that if you are invited, someone uninvites you, then you can plus one yourself.
But if you bring a plus one they can me minus one'd and you can't do anything to prevent it.
- someone uninvites you, then you can plus one yourself.
  No, self-votes should not count because then everyone will just self-vote and no actual consensus building is taking place.
  If you get downvoted, hope that you have at least one friend who cares about you being there
- Hmmm this is actually pretty genius.
  If you think someone might not want you, but you really want to be there, plus one yourself.
  But if two or more people minus one you, then you're still not going.
What is this math you speak of?
- It’s maffs bruv
Based on the progression of BIDMAS/PEMDAS, addition always is first, followed by subtraction.

  Addition and Subtraction in any order actually. The mnemonics are just a way to remember the rules - like a mental checklist - they aren't the rules themselves
- Incorrect.
  Addition and subtraction are equal priority, left-to-right.

Even one of the engaged?

you can uninvite one person of your choosing
According to the terms, yes. Shoulda said "guest."
Prevents objections

Can I uninvite myself?

List of people

Everyone gets two votes. Can vote people up or down

Everyone with negative votes can't join

Ngl, I'd un-invite someone from the wedding party just to sow chaos.

Dear Mr. Holloway.
I will be attending your wedding. I choose you as my Minus One. Please do not show up.
Bless,
