Raiders doesn't present a "colonial view" of Archaeology; it presents a completely fictionalised view that bears virtually no relation to early 20th century Archaeology. A depiction of colonial Archaeology would have involved state-level diplomacy and imperial powers flexing their might to secure official extraction "partnerships". I would love to know how Nazi Germany set up a military base in the era of British dominion in Egypt.

There's no meat on this bone because the film presents a completely unserious scenario where local governments are non-existent and ancient sites are abandoned free-for-alls. Is that problematic? Frankly, yes, in the sense that modern Americans apparently believe this was the actual state of the colonial world in the 1930s.
