The main difference between micronations and microstates is that micronations are not recognized countries, while microstates are recognized countries (Andorra, Monaco, San Marino, etc).
But this small countries recognized by ONU and several international organizations like Andorra or Monaco are the main objective of most micronationalists.
A lot of rich libertarian bussinesman are investing in free-communities like Liberland or the Seasteading Institute. This libertarians want to create little countries searching the sewers of the law with the aim of proclaming the independence of little spaces of the world. Normally this spaces are locaated on international waaters, or in ''terra nuilius' land, etc...
That is to say, the main objective of this libertarians is to create their own law in some places of the world, of course I am talking about tax heaven.
No matters that most of politicians and lefties are claiming for the fight against Tax Havens. If all tax havens desapear, and then one libertarian get its objective of creating its own micronation and implanting a tax haven system in that micronation, this tax haven would be the most important Tax Haven in the world, because it will be the only one.
This is why micronations are being supported by very rich people and inclusive by popular people fed up of paying taxes for everything and several times. Micronations are the alternative to those tax hells which are invading the world.
Micronations have been born together with a political idea, the idea of freedom. As you have seen in the last days, some Catalans want to secede from Spain. A lot of regional political parties are claiming for independence in a lot of Europe's regions. But if you look to some catalan rallies for independence, you will notice that there are more european flags than catalan flags. Why?
Well, they don't want to secede, they want to live better. They think that for being''independent'', they will have a strong economical capacity. Perhaps is true. What is true, is that if this regional political parties become strong, we will see a Europe of Regions, or perhaps a Europe of Micro Regions. If Catalonia becomes a new state, the Valley of Aran, can be also an state. If the North of Italy becomes a new state, Seborga can do so. We are seeing that a lot of micronations are cliaming for independence. For instance, they have a problem of legitimacy. So many people think they are jokes, but they aren't. If we see regionalism growing, we will see also micronationalism growing. Europe is plenty of microstates: Andorra, Monaco, Liechtenstein, ....
What if Europe respect Seborga, Pontinha, Tavolara and so on, also as microstates?
