Some services provide tools that may or may not be used for piracy, such as a VPN or Usenet indexer. Bitcoin conducts transactions peer-to-peer, there's no intermediary to prevent the funds from rolling in. As a result, many of these services utilize Bitcoin as their only method.
As of now, bitcoin is just an option for most of the stores whether it is online or offline because bitcoin is not yet famous in most of the people in the country so if bitcoin will become the only method to pay then people will get confused and they will think suspicious about bitcoin. It is better to slowly introduced bitcoin to people before declaring it as an only method.
With such circumstances it is not surprising that few people who use bitcoins for their currency or payment methods. besides the problem that expensive fees also burden them. most users prefer to use bitcoin for their investment and profits. I think even though you declare bitcoin to the public and bitcoin is famous though. users will be a little lazy to use bitcoin as payment. because the fee is very expensive. maybe they think that it would be better to shop and pay using fiat that without a fee
