Who said it is a UBI that this "rebuttal" even makes sense to appear here? The Irish government isn't calling it a UBI. The article doesn't call it a UBI. Even the FAQ for the program says it is not UBI:
>> Why this is not a Universal Basic Income
>> It is important to note that that the Basic Income for the Arts Pilot is not a Universal Basic Income. This is a sectoral intervention to support practicing artists and creative arts workers to focus on their creative practice. This policy is separate to the Universal Basic income as outlined in the Programme for Government.
