Presumably there is some time component, i.e you need to use the machine quickly or risk losing it.

Also, it's better to double $2 instead of $1, and then pay back that $1.1 and end up with $2.9 instead of $2.

But it was a more facetious comment than I would have preferred to make, I actually went to delete it but you got in too quickly.

There are many reasons it's wrong, too, eg. at some level of risk debt becomes more expensive or impossible

But the intent of the comment was to say that if you owned as sure a thing as the GP proposed you'd do what you could to avoid selling parts of it.
