Although you pointed out that fees in Bitcoin are frequently perceived as needless, they are actually crucial to maintaining the security and stability of the system. That cost? It serves as a barrier against dangers from without as well as a means of payment.
Fiat's centralized structure has repeatedly demonstrated to us that it is vulnerable to fraud, inflation, and corruption. The paradigm that Bitcoin challenges forces us to consider a more egalitarian financial future. Bitcoin has the potential to displace traditional currencies as we go farther into the digital era. When rather than if is the question.
Bitcoin can replace traditional currencies (Fiat), but that will never happen. That's because governments won't allow something decentralized to dominate the mainstream economy. It will be less power for the government, and more control for the people. Despite Bitcoin's inability to replace Fiat, it's still the best thing around to protect your financial freedom. BTC can't be debased, confiscated, or frozen at will.
The fees are the only price you're paying to enjoy the benefits of decentralization and censorship-resistance. This is a lot better than having to use a heavily-manipulated currency (Fiat) that can lose its value anytime. The more people join the Bitcoin train, the faster Fiat will lose its dominance in the mainstream world. Some countries are beginning to adopt BTC as legal tender, so expect the unexpected. Who knows what the future lies for the cryptocurrency? Just my thoughts
