Nutrition would not be a problem, we have enough food but we waste it for animal feed.
Would it make sense to cut the subsidies, let animal product prices skyrocket, but then put the subsidies on the consumer side so overworked underpaid workers could maintain their diets? Apart from that, it seems a bit shitty that vegan taxpayers still finance animal exploitation by simply paying their tax.
This is a central demand from the IPCC and many governments have come to the same conclusion but most just talk about in the backrooms. In Germany there are plans discussed about raising the tax on animal products but that will not be enough (80% of the subsides go to the animal industry, they create damages of about 90 Billion € each year which are not accounted for)
For the EU it is 82% of the subsidies that go the animal industry: https://phys.org/news/2024-04-eu-farming-subsidies-emissions-intensive.html
