In my country, bitcoin can't be used as a payment currency so I didn't think about creating a business with bitcoin payments. But on the other hand, bitcoin is not popular in my country so if I open a business using bitcoin as payment currency it will have a bad impact on my business. I will focus more on business development and use the most common payments people make so that my products can be purchased easily. If my business is advanced and I can collect a lot of money, that's where I will start buying bitcoin. I think this way is more logical for me than forcing to create a business and accept bitcoin payments
It's not a problem when you sell your product outside of your country, because you can accept and use Bitcoin for global payment. For example today, you have received a payment signature with Bitcoin even working in the Indonesia area, right? So with this situation, I think it's not a big problem so far, except if you sell your product on an online shop where you are restricted just use payment Rupiah. I have a friend who has been selling digital products since 4 years ago, he is fine today, not been banned even he only accepted payment PayPal and bitcoin. Because he sells in outside the country. but even if not accepted his local currency, he still pay tax after he exchange his bitcoin to local exchange. he can still contribute to his country.
I think you are misunderstanding the reply that you quoted. If I'm not mistaken, he's referring to physical business and not online businesses. If you are operating physical business, forcing your customers to make payment with bitcoin will actually have a negative impact on your business. Of course you can introduce it as one of your payment method but enforcing it on customer is not a proper way to expand your business. It'll be easy to do when you are running online businesses. Adopting the most popular payment methods in your area is a great way to make your products accessible to as many people as possible. If Bitcoin is not legal in your country, you need to carefully consider the risks and potential consequences of accepting it as a payment method.
