There are some people with the means. Someone like Jeff Bezos could pull it off, instead of or in addition to shooting rockets into space. He could offer Brazil jobs (moving some Amazon centers there for example), he could raise the cash to "rent" the Amazon, and he also has the tools at his disposal to control that the agreement is honored, by analyzing satellite data for example. He might even be able to turn that into another profitable business, using the same technology for monitoring crops or similar. If he offers a good enough package, Bolsonaro could not refuse it.
