Because i’d say yes we should allow that. We in the us and canada have governments that are proven to be unresponsive to the will of the people without the people giving the government a shove from time to time. If the majority supports a cause, the government should act - if it doesn’t, let the economy suffer until they do.
I also believe a different test applies when we’re talking about indigenous land. I.e. it’s no longer about a majority of the population - it’s about a majority of the people who’s land it is.
