must have actual land
Mentions Sealand

https://en.wikipedia.org/wiki/List_of_micronations

I’d have a couple of options:

Most Serene Federal Republic of Montmartre

This republic, retroactively dated to 1636, encompasses the Theater District in the borough of Manhattan, in New York City. In the late 1970s, a dispute between Montmartre's founder and New York Telephone, over whether the micronation could be listed in the government pages of the phone book, ended up in front of the New York Public Service Commission. The commission vacillated, alternately issuing rulings in favour of each party, and listings for the republic did appear in at least a few editions of the New York Telephone book.

All of life is basically a series of interlocking musicals, and I’d aim for some ministerial position. I’d like to work for the Idina Menzel administration.

Nation of Pacifica/Cascadia

This one isn’t on the Wikipedia page for some reason, but it’s a pretty active concept.

It’s basically the west coast states and territories, ranging from British Columbia to Baja California, with the idea of being some contiguous subset of those areas. I’d just want to make sure it includes the Bay Area and LA.

Also you can't just make your own micronation wherever you want. It has to already exist.

This kind of makes the concept of a micronation useless. The point is that anyone can make their own nation with their own rules wherever they are or go. If you have to pick someone else's, then it's no different than picking someone else's recognized nation.

Does the vatican count? I'd get into the archives and make it my lifes work to find all the secrets.

Plus it's pretty cool there, there's people who do spend their lives there, and always visitors from round the world to hang out with.

Luxembourg is awesome. Easy pick

The closest to me AFAIK is Sealand, but I'd rather not, tbh. I do actually have a passport from Waveland, declared as part of a Greenpeace campaign some years back and based on Rockall, but also not too appealing as a long-term residence.

At one site that I lived and worked on for several years, we discussed declaring unilateral independence on several occasions. It was a shingle spit nature reserve and seemed a promising location, but we never did. Well, not so far.

Overall, the Free Borough of Llanrwst looks a good bet. I have been there and definitely enjoy the area.

This post is assuming I know what the fuck that is or what one is. I choose Petoria

The Other World, Czech Republic: "A BDSM resort specializing in female dominance, located in a château in Černá, Žďár nad Sázavou District, claims to be an independent matriarchy."

I visited Molossia a while ago, dude was awesome and super friendly. Plus the weather in Molossia is always perfect, although with the close borders with Nevada sometimes the bad weather from the US bleeds in.

Monaco, no brainer.

Never seen so many bucks per square meter.

Christiania of course!

Are there any good ones? Am I allowed to launch a coup?

Lichtenstein or Andorra

https://en.m.wikipedia.org/wiki/La%C3%A0s#Principality_of_La%C3%A0s

Being in a temperate part of France sounds pretty great, especially if I got a room in Chateau de Láas.

The one with the fastest internet.

As long as I can have satellite internet and have supplies delivered, I'm picking the Kingdom of Redonda.

Can I afford it if I choose some place like Monaco?

Are there any in the EU with a nice beach?

Does the Vatican count?

Seborga! Been there often.

Pitcairn

The Republic of Jämtland, very nice place. I even have friends there.

New Freeland.

I was awarded the Royal Decoration of Saint Michael the Archangel from the Principality of Kaharagia, so that would be my first choice, since I’m a Lady. Last I knew they were still looking for land, though, so that may be out.

~~Second choice is Monaco.~~

e: didn’t realise Monaco is officially recognised.

In that case, The Republic of Saugeais.

Tuvalu

Black Rock City

Probably Sealand.
