I mean... let's be real... a rich person will answer the knock, follow the police peacefully to the police car, and the only thing they'll say and do is "i want my lawyer"
White collar criminals shredding documents and wiping hard drives is not unknown.
The purpose of a no knock raid is, in theory at least, to stop people destroying evidence. They only incidentally turn into shootouts, that's not what they're intended for.
In modern times.... with hard drive encryption by default, and mostly paperless work, any sort of criminal, who can afford a house like that, doesn't need to run into the office, and start the shredder, while the police are knocking on the door.
