Why not?
If humanity wants to survive more than a few million years, it needs to reach the stars and colonize other planets. Here on earth, we could be wiped out tomorrow by an crashing asteroid, or we could reach the end of resources and devolve back to apes. In any case, the sun will extinguish itself in 4.5 billion years, engulfing the earth as it becomes a red giant. The doom of earth is a 100% certainty so is the doom of the solar system. By then we better be all over the galaxy if we want to survive.

Because it is good business. For every $1 spent by NASA on space exploration and other space related activities, $7 are leveraged and returned into the economy as new business, technology and products get developped.
Plus all that money is spent paying working people's salaries, it is not wasted; those people would be dirt poor without their job...

In case you've been sleeping in a hole for thirty years, we need to get the hell off this planet. Mankind's only hope is to seed the universe beyond.

Because the human race is destroying Earth and we need to find other planets that we can go to.

Because it is really hard to do. If we knew any cheap way to do it we would use that. But cheap ways will never be discovered and developed is we just give up now.
