Clearly the only way to change that would be to restrict the number of persons able to legitimately work as archaeologists. The only ways of achieving that are through either qualification or licensing or some combination of both

How will that restrict the number of freshly-qualified archaeologists seeking to work in archaeology? Anyone who seriously wants to be an archaeologist, currently gets an undergrad degree (like it or not, that's the de facto entry qualification these days). Anyone who seriously wants to be an archaeologist would therefore go and get whatever new qualification is required. The only way you'll restrict the numbers doing so will be to a) make it prohibitively expensive and out of reach for many, or b) implement a cap on the number permitted to qualify/register per year (illegal, I should imagine).

I think the currently increasing costs of taking a degree, plus the scaling-down/closure of university archaeology departments, are more likely to stem the flow.
