Britons are applying for Irish citizenship to get an EU passport. Is this a problem?

Since the Brexit vote, many British citizens have sought citizenship in other EU member states – notably Ireland – on the basis of ancestry or other provisions, often without any intention of living there. Should we welcome this development? Or is it problematic that people can claim citizenship on the basis of ancestry, especially if large numbers do so? Iseult Honohan argues that while extending the right to citizenship down multiple generations is a questionable step, problems will only really arise if citizens who have never lived in the country are given equal voting power.
