Can I buy my domain permanently?

Could you please clarify for me? Is it possible to purchase a domain name indefinitely, ensuring its perpetual ownership under my control? I'm curious about the terms and conditions surrounding such a purchase, and whether there are any factors that could potentially affect my ownership status in the future. Could you elaborate on the steps involved in acquiring a domain name for permanent use, and any associated costs or responsibilities that I should be aware of? Thank you for your assistance in addressing this inquiry.
