I think that no one believes killing consumers of these products is a viable solution or that it doesn't have disastrous side effects. What happens with rhinos that die? do we have to collect their tusks and these are rad-waste now? Making them radioactive with non-penetrating particles might be ok from the standpoint of trying to make them less desirable... but you aren't making them detectable & it is highly controversial to do this. In reality, and back to the solutions proposed by the article: I don't know if the source article's idea has merit or is just funded by a non-profit where this is a small pet project or if they really don't understand the tradespace.
