> How did you first obtain your crypto? What level of anonymity was available for that tx?

Suppose you mined it or received it as payment for selling something to a stranger who doesn't know your identity.

> Where do you store your crypto short and long term?

If you're using it as a payment method you don't store it long-term. You either spend it promptly or convert it into some ordinary form of investment.

> What are you buying with the crypto? Why does it need to be purchased with crypto?

Whatever you want to buy with it. Suppose you want a VPN subscription. Suppose you want to make an anonymous donation. Suppose you're just eating at a restaurant and don't want a record of that on your bank statement.

> Where are you having it shipped?

There are lots of things you can buy that don't need to be shipped.

Also, that's a separate problem. If you actually had such requirements then you would have to deal with them, but first you'd need to solve the problem of not having a charge for the thing you want to be private appearing on your credit card statement tied to your government ID.

> Why do they need to use your specific crypto coin? Why can’t they use a locally invented (read: forked) one?

Because a major benefit is to be able to make transfers between countries.
