Other than possession? The technology required to harvest them is far more advanced than the tech required for an ICBM, so anyone who can I get there, I don't think will be paying tribute.
This is actually a field I've thought a lot about, in no small part because whoever solves this problem stands to profit a lot.
The problem is time horizons. Extraterrestrial mining projects from conception to first delivery is probably a 20-30 year timeframe. That is way, way outside of what could be reasonably financed on the open market.
On the other hand, if you could reasonably get a return on investment in the 5-7 year time frame, then there'd be no trouble getting financing for each step of the project. However that requires having liquidity events before you're able to actually get resources to market, and the only way I see that to be possible is to sell some sort of contract valued by future revenue potential. You see the same problem in remote areas of the Earth where mining efforts take considerable planning, e.g. northern Canada. And we have solutions there: mining claims and a sense of legal ownership of resources that are still in the ground.
Break that mining project into 5 to 7 year chunks with a mechanism for contracts exchanging hands inbetween, and the free market will solve the problem of bootstrapping space settlement.
