You're thinking about this wrong. As long as we can send probes and/or communicate within compressed timeframes than physical transportation of humans doesn't matter.

E.g. Breakthrough Starshot can get us to many exoplanets within 20-30 years: https://en.wikipedia.org/wiki/Breakthrough_Starshot

"Many" exoplanets? How many planets does Alpha Centauri have?

It is ~4 ly away. If you're willing to go ~10 ly, you get 6 more stars to look at. And it gets far worse from there.

It's now estimated there are more Earth-sized planets than gas giants on most stars, and that every star has at least 1 planet, likely more.

So that's 7 or more planets. That's many.
