The tools you'd need on Mars are: Electric mobility and energy storage, launch vehicles to cheaply lift satellite constellations to Earth orbit (which just so happen to heavy lift what you need for a Mars transit), cheap tunnel boring to reduce transportation congestion on Earth, but also to build underground (radiation protected) habitats on Mars.
If you have a hobby you love (go to Mars, die on Mars), it doesn't hurt to get rich building the infra your hobby needs. You will need those funds to buy services from your companies for your hobby.
