It doesn't actually matter. A addiction will ruin lives if unchecked. No matter if physical or psychological. It's all about definitions at that point too.
Where does physical end and where does psychological start.
The terms “addiction” and “dependence” can seem similar, but they are different. Dependence occurs when the body physically relies on a drug. Addiction involves changes in behavior. A person with an addiction has difficulty not using substances or doing rewarding activities, even if it is harming them.
The difference between addiction and dependence can be difficult to understand. Some organizations have different definitions, use the words interchangeably or even abandon both terms altogether. (Substance use disorder, or SUD, is a preferred term in the scientific community.) Because of this lack of consistency, some ground rules can help differentiate between the two terms.
When people use the term “dependence,” they are usually referring to a physical dependence on a substance. Dependence is characterized by the symptoms of tolerance and withdrawal. While it is possible to have a physical dependence without being addicted, addiction is usually right around the corner.
You're the one being disingenuous. The issue here isn't related to the word "addiction" vs. "dependence".
This issue is the use of the word "physical", which you seem to be deliberately avoiding offering any explanation for.
Tik Tok cannot be physically addictive, because "physical addiction" is exclusively related to physical substances, like alcohol, recreational drugs, and medications. You cannot physically consume Tik Tok and become chemically addicted to it.
One could become addicted to the stimulation of Tik Tok, or dependent on it emotionally, but they literally cannot become physically addicted to or dependent on it unless "Tik Tok" is actually a slang term for a drug or something...
