I agree current solar system would be easier to colonize and definitely economically more sensible but I do think that when lifetimes expand to be 100s of years, that the timelines on what you can invest in would expand accordingly. For example, the longest timeframe in pension fund investing is 25 years. Which is 1/3th of a lifetime. If lifetimes increase by 10x then the timeframe would become 250 years and mineral explorations of other solar systems becomes a feasible financial endeavor.
