We might find it quite difficult to extract from the stars, that said.
It might be expensive compared to improved Earth mining, but lunar regolite is rich in Helium 3, there would be no need to mine stars.
The funny part is, lunar regolite soaks Helium from its exposure to solar wind, so mining it would be an indirect mining of a star, our sun.
It is pretty much impossible to extract it from stars, but the 4 big planets have large amounts of helium.
It would be quite expensive to extract it from there, due to the necessity of escaping from their gravitational field, but not impossible.
If we have such advanced tech, and trip to big planets would seem economically feasible, I think we will be long beyond the point of desperately needing transporting helium to do such crazy trips.
