Yes, but if several thousand tons of iridium, platinum, or various rare-earth metals could be captured & towed to Earth orbit, the payoff could be astronomical.
Suddenly there would be so much of a supply that the sale won't be profitable any longer. That's probably the reason why no one is extracting rhodium from nuclear waste, where it is a common fission product.
I've been told that the trucking industry needs every year more platinum than has been mined in all of history. Since there obviously isn't supply they instead use alternative means to achieve their emissions goals.
I'm not an emissions system engineer so I can't evaluate the truth of the statement. If it is true, and supply existed: it would create demand, potentially it could even drive up price as potential users quit using less desirable alternatives.
The demand is mostly in chemical industry and very inelastic. No one is going to put another plant on line because platinum group metals are cheap (but plants may be pulled off line because the economy is in the dumps, as happened in 2008 and 2017). Even small increases in supply will lead to great drops in price. You can only hope that a plentiful supply would encourage new uses.
