Accused by rightwing extremists of plagiarism?: you can't be a college president.
Take control of a country by illegal force and then extort your way to someone else's non-transferable trophy?: So much winning that you should be able to cancel the midterm elections.

Update: turns out you *can* hardcode equation numbers that will temporarily override auto-numbering. If using Quarto (which I am), you've got to have all numbered equations and cross-references in a Typst block, which means you can't use Quarto's native equation cross-referencing.
![## First equation slide
Here's an equation that gets auto-numbered by Typst:
```{=typst}
$ sum_(i=1)^n x_i = (n(n+1))/2 $ <eq-sum>
This is the sum formula.
```
## Repeat of Equation 1
Here's a repeat of equation (1):
```{=typst}
#set math.equation(number-align: end, numbering: n => [(1)])
$ sum_(i=1)^n x_i = (n(n+1))/2 $

In mainstream climate econ, preferences are usually assumed to be well-behaved and to avoid standard behavioral econ foibles. But even in that context, a common mistake is to insist that the correct discount rates to use in policy evaluation will be some interest rate or other.
