From wikipedia: “Pirate Party is a label adopted by political parties around the world. Pirate parties support civil rights, direct democracy (including e-democracy) or alternatively participation in government, reform of copyright and patent laws to make them more flexible and open to encourage innovation and creativity, use of free and open-source software, free sharing of knowledge (open content and open access), information privacy, transparency, freedom of information, free speech, anti-corruption, net neutrality and oppose mass surveillance, censorship and Big Tech.”
They don’t have to cover everything. Pirate Parties often ally with other parties that cover other specific problems, e.g. Piratenpartij & De Groenen (“Pirate Party” and “The Greens” alliance) in Netherlands, and they work well together.
They absolutely have to cover everything. The idea of voting a politician into office knowing they aren’t competent in all aspects of their job is wild to me.
Am I going to vote for an MP that has no knowledge of policies on healthcare, welfare, etc? Of course not, that would be deeply irresponsible.
This might be OK depending on your location and the government system in place. Voting for a single person that has to answer all questions sounds like UK or US to me.
Take a look at the Finnish or the Dutch parliament. 7, 8, 16 parties there? Independent (no-party) politicians too. Each one of them is free to represent people with specific needs and only focus on that.
Also keep in mind that some questions like “healthcare” and “welfare” may be less relevant too. It can be pretty much resolved (you can always promise to “increase doctors’ wages by 30%!”). More specific issues remain.
