Do Micronations Hold Power?

There is, in reality, no substantial difference between sovereign states, secessionist states or nations, and micronations. There is, in reality, no substantial difference between the Official World (First, Second, and Third World nations), and the non-Official World (Fourth, Fifth, and Sixth World nations). Any and all the perceived differences are little more than a con game of the de jure states at the expense of the competition, at the expense of the less de jure territorial and non-territorial entities.

Secessionist nations can be macronations or micronations. They can even enjoy some de jure or de facto recognition. These are all Fourth World nations regardless of size.

Non-secessionist micronations either don't have land claims; they claim their backyards/gardens only; or they have irredentist claims. Non-secessionist micronations can also enjoy some de jure or de facto recognition, although this is very rare. These are Fifth World nations if they are older, or Sixth World nations if they are younger.

Some secessionist nations enjoy the recognition of a few sovereign states, but they also may enjoy the recognition of de facto states.

There are also some non-secessionist micronations that enjoy recognition, but this is usually either de facto recognition only, such as recognition of their passports, or it is recognition by IGOs or international NGOs (INGOs).

The basic issue is this: recognition is not like an on-and-off switch, but more like a variable resistor.

Most UN member states enjoy full international recognition, or are lacking the recognition of only a few states. However, there are also states like Israel which enjoy a lot less than full international recognition, and also states like Taiwan which are not UN members despite substantial recognition by sovereign states. There are also some secessionist nations which enjoy the de jure recognition of only a few sovereign states, and some micronations enjoy the recognition of IGOs and/or INGOs.

For example, the United Micronations Multi-Oceanic Archipelago (UMMOA) is recognised by an IGO of states, by an IGO of emerging states, and by several INGOs.

So it is not true that micronations are not recognised at all, and if they are recognised they are not micronations anymore.

Even the people of San Marino make up a micronation. However, San Marino also happens to be a sovereign state, a microstate, which enjoys full international recognition.

In fact micronations hold power over their citizens or "members" in ways of laws, constitutions, bill of rights, and other legislation or documentation set forth by it's de jure governmental bodies.

The Montevideo Convention on the Rights and Duties of States is a treaty signed at Montevideo, Uruguay, on December 26, 1933, during the Seventh International Conference of American States. The Convention codifies the declarative theory of statehood as accepted as part of customary international law. the first sentence of article 3 explicitly states that "The political existence of the state is independent of recognition by the other states."  micronations and other unrecognized states have used the Montevideo Convention as justification for calling themselves sovereign states. As the convention states that a political entity must merely "declare" itself to be sovereign, most micronations consider their public declaration of sovereignty to be evidence enough of their status as a sovereign nation.

Example is I'm the ruler of a micronation known as the Suquelish Republic. The Suquelish Republic used as a argument under International agreements and treaties that confirm that microstates/micronations have a right to sovereignty. The Atlantic Charter reads: “respect the right of all peoples to choose the form of government under which they will live.” This was signed by the US, the UK and many other nations in 1941. In a similar notion, the International Covenant on Civil and Political Rights, signed in 1966, states that “All peoples have the right of self-determination. By virtue of that right they freely determine their political status…” Self determination is the right of people to rule over themselves and create their own state. These treaties clearly state that people have the right, under international law, to create their own nation and rule over it freely. The Treason Act of 1495 which states that “An Acte that noe person going with the King to the Warres shalbe attaynt of treason.” (Preamble) This is generally interpreted by scholars as any person acting as the de facto sovereign in a member state of the Commonwealth of Nations will be considered the monarch and it is thus illegal to deny their reign. 

Yes micronations are real and have real power under international laws.
