Recent articles have pointed out how collecting houseplants from tropical regions can do more harm for the environment than good due to having to import these specimens into the country.
If this is something that you are concerned about then don't hesitate to contact your local nursery or gardening centre and see where they get their plants from. See if you can source a company that grow their plants in your country rather than shipping houseplants in.
If you're feeling torn to the extent that you don't want to cause damage to the environment but you really want to add an Alocasia to your collection then why not find someone else who wants this plant and do some root division or propagation. You can even grow the plant yourself and divide out segments for your friend and family so more people can have access to the plant without having to ship it in from abroad.
