If you ever run an ecommerce business, the expectation is absolutely that you pay taxes to foreign governments in compliance with their rules for any customers in their jurisdiction.
Is this usually followed in small scale shops? Almost never in my experience, though if the shop gets big enough or if the business is sold those tax liabilities are still technically owed. Many countries do have a minimum revenue before you have to pay taxes, and some have a minimum before you're supposed to report sales via tax filings even if you don't owe, but you better keep the operation small if you never plan to pay foreign sales tax.
