You mean it’s easy to eat a shit ton of CALORIES when when eating carbs? Carbs are just easier to over eat. It’s much harder to sit down to eat 600 calories of lean, grilled chicken breast (185 calories 4 oz serving size) than it is to eat 600 calories in typical “indulgent/mindless” carbohydrates, such as the aforementioned bread. 4 dinner rolls with 2 tables spoons of butter is easy 600 calories with little to no protein. However, I dare you to eat 600 calories of plain potatoes. It still comes down to overeating eating calories, and skipping skipping carbohydrates is just an easy way to reduce.

Additionally, from my understanding you need to meet a much lower threshold of carbohydrates (sub 30g) to enter ketosis. You can also enter ketosis with time restricted feedings (intermittent fasting) if that is desired.
