And you’re saying it’s absolutely impossible to exchange meat in such a way as to not increase the incentive of meat being killed to be consumed in the future?
What do you mean by "exchange meat"? I assume you mean exchange value (i.e. money) for meat?
That's a very unlikely exception though. If you go to the grocery store and buy some meat, there is no basis or evidence to believe they're only collecting roadkill. When you buy meat from a grocery store, it's virtually certain that this is increasing the chances of animals being killed (very often after being subjected to extreme suffering). And you will have a share in the responsibility for those effects, because there's a causal link between your choice to buy the product and the things that are done to make it available.
