That's just a question of how long it takes to get there. You accelerate until you've spent half your fuel, then coast for as long as it take, the decelerate with the other half of your fuel.

And if you're boosting an actual gravity source (i.e. an asteroid), you can jump to and from that in mid-flight, ferrying extra fuel. Though if you're boositng an ice asteroid, that wouldn't be necessary.

But yes, it's not something I'd expect governments to undertake unless they take an exceptionally long view.
