There is absolutely no way beef spikes insulin as much as rice does. Beef has zero carbohydrates and while some protein does convert to glucose, it is a slow process and thus the insulin response will still be much less than if one consumed the equivalent of carbohydrate in rice. This is further slowed by digesting the fat in the beef.

""Between 50–60% of protein becomes glucose and enters the bloodstream about 3–4 hours after eaten." Perhaps 50–60% of protein goes through the process of gluconeogenesis in the liver, but virtually none of this glucose enters into the general circulation."

Are you suggesting that insulin only responds to carbohydrate intake? I understand insulin plays an important role in shuttling all macronutrients from the GI tract into tissues, even if that action is somewhat different for fats, proteins, and carbs. (ie insulin binds to fat cells to reduce fat mobilization in a fed state)

Here you can see while its not the exact same, the insulin scores of beef & rice (brown especially) are very close to each other. Definitely much closer than most popular culture advice would suggest.

But it should also be said that this is for healthy individuals.
