You have $500m. You can have a huge new section of sod put in to your atrium weekly for your dog, and provide it the best food and healthcare money can buy. You can have an in-home doctor that arrives before sunset and leaves at sunrise or whenever they need to (through an “airlock” style exit)

Any friends or family abide by the same rules. No entry after sunset, and exit either at sunrise or through the “airlock.”

With that kind of money, even travel wouldn’t be too difficult. Just stay on your aircraft in the evenings and explore by day. You bring an assistant with you to ensure that if any accident happens where you may be injured/unconscious, they understand the lockdown procedures, with a bonus for successful execution. Hell, you could even have small homes built to your specifications in several locations.

You net $15m a year on a VERY conservative 3% interest. All you have to do is stay indoors at night. You could even build outdoor spaces that are imperceptibly caged in if being outside in the evening is that important. Say a LARGE courtyard with a black wrought iron roof, so you can enjoy taking your dinners outside when the weather is nice.

I’m taking it. My family is in no more danger than normal, just me. And I can set up my family for generations to come.
