So at what point did bitcoin start losing its identity?
Bitcoin will always remain an alternative to fiat and I dont think it will ever lose its identity. Many people use Bitcoin as an asset and a hedge against inflation but there are still people who use it as a currency. Some countries have some restrictions placed on banking activities. In my country, you might not be allowed to transfer more than a certain amount per day. There are some businessmen who use Bitcoin to pay their business partners. While some individuals see it as the best means to carry out international business transactions. However, due to its high volatility and unfavorable government policies, might continue to be used as an asset.
