The Times of Israel article.
TLDR summary: The US can easily take Kharg Island, but then the Iranians will beat the !!!!! out of them with FPV and Shahed drones, which they're not currently set up and trained to defend against. If they want to stop Iranian oil exports it would easier to stop and seize tankers after they leave and/or bomb the oil export equipment on the island.
My comment - main customer is China who have moved a naval force into the Gulf to escort their tankers inbound and outbound, I don't think stopping the tankers is a realistic option as it risks a confrontation with China.

Taking Kharg Island is seen as key to opening Hormuz. There are better options
