There are 2 directions to think of:

1. The economic principles and the politics used by governments today tend to make the country's legal tender inflationary, which makes people that hold money poorer every day. Bitcoin is the opposite, it's deflationary, so it becomes a viable alternative. Of course, this can be seen as "for profit" use, although I see it as the best way to fight inflation (which is avoid stealing, not actually earning).

2. The world has shown us in the last 1-2 years and will continue to show that democracy is just a lie. People are lured to vote with people they don't really believe in just because of some empty promises or because they are fed up with "the others" and this was the only alternative. Lately democracy has become a vote against somebody because neither of the alternatives are good enough.
So the current democracy is to pick your choice between options, none of those options being good, none you like. So it's a lie. Since there's no correct/true democracy we cannot trust the legal tender.

I believe bitcoin will be accepted by many countries with a democratic society, but we need the process to reach it gradually and now there are several countries with large communities they are already enjoying the benefits result from this bitcoin

There is difference between democracy and democracy, so I want to say that the democratic standards are not samo in all so called democratic countries. But on the other hand democracy helped Bitcoin to develope and maybe slowly but certainly is getting accepted and approved.

Fun and profit are pretty unimportant when compared to physiological needs of people. If ones lives in a democratic society there probably are myriad different ways for him to profit or have fun without having to use bitcoin to achieve such goals.

Who needs Bitcoin in a democratic society?

The minority.

Who needs Bitcoin in a democratic society?

Those of us who don't want to disclose all our taxes, those of us who don't like being fucked by our government & banks every year. Bank savings interest rates are fucking disgraceful.

Everything. Only a government has the power to prohibit certain transactions. This is known as capital controls.

Bitcoin, thanks to it's decentralized nature, allows for censorship-proof transactions, regardless of what some "authority" says.

It also allows users to protect their wealth with an asset that, secured properly, can not be seized without the explicit permission of the private key holder.

Tax avoidance in a legal manner sure sound appealing but also not quite an absolute need. I do however agree that cryptocurrency poses a unique way to avoid tax under many jurisdiction due to how new it is.

Well.. Bitcoin is Counterfeit-secured.
So even if you dont need Bitcoins.. it still would be a better option than Fiat (paper) money.

Further BTC could be used as "consistent" Currency. To be able to pay the same price on the internet (from everywhere).
