I also feel that a good solution of the Fermi Paradox is that interstellar travel is either impossible or too unpractical at scale and that humanity may be trap

  I believe that that Fermi Paradox is not a paradox at all. It's just a poor set of assumptions. Life is likely extremely rare, and intelligent life is likely astronomically rare. Technological interstellar traveling life does not appear to exist anywhere in our Local Group. The Local Group is only 10M light-years across. A single technological species that had arisen on any of the trillions of planets, traveling at 10% the speed of light, would only need a 100M years to colonize the entire Local Group! We are alone, or at least the first. This is a good thing if you look at how we treat "lower" species on our own planet.

    > would only need a 100M years That's an enormous span of time. There's no reason to believe even a technologically advanced civilization would survive for that long. Let alone maintain the impetus for constant colonization. We gave up going to the moon in less than 10 years.

      Yes, but in the local group there are many, many trillions of planets. That’s a lot of chances at bat. The more commonly used example is our galaxy, which would only take 100,000 years at .1C, and has many hundreds of billions of planets.

  The Fermi Paradox is about the (intelligently-created) radio silence, not the lack of little green tourists. We'd eventually notice an advanced civilization in a period that intersects our time/distance coordinates (i.e., if Alpha Centaurians had radio 4-1/2 years ago, we'd probably hear it). But otherwise, yeah, we're imprisoned here by 'c'.
