>Delivering stuff home is the easy part.
I imagine most asteroids are in the belts beyond Mars or beyond Pluto even, i.e very far away. If you plan to mine Moon exclusively that's another story and I don't see a problem with that immediately but honestly the biggest thing I heard that we need from there is tritium for our maybe-to-come nuclear fusion reactors but I am not too optimistic about those either.
>And your changing state thing is wrong
No, I meant just chemical change, not changing of elements. Whatever we do have, we have probably enough for eternity if we learn to recycle.
>they have relatively high concentrations of multiple elements that are tough to find on the Earth's surface.
That is nice but I am not sure how useful it is if we already have enough. I am not entirely aware of the situation in the respective industries/fields and I suppose they wouldn't say no if a giant iron/silver/gold asteroid suddenly appeared before their eyes but as I said, such efforts probably wouldn't be free. What's cheaper?
>There are some things that actually benefit greatly from manufacturing in microgravity.
OK, I didn't know that, I guess it's legit but the question if it's worth the effort still stands. I mean, it's not even me who will be asking the question, it's all the moneybags you would want to get funds from.
>The actual "getting factories to space" is another thing that is less hard than people think.
Well, we don't even have a base on the Moon, so add a decade or so to any such project lol.
And again, I am fairly pessimistic about any human-manned expeditions to space. Apart from low gravity wrecking your body, there is always a problem of space radiation and with bigger distances (like the one to Mars) you cannot even rotate people from there. And robots are dumb. Eternal despair.
