I think there is a mistake in the calculation:
Price (in THL donations) of veganism = 1⁄45 71.1 / 3.4 LIVES (instead of YEARS)/$
= $0.46/life. Assuming most lives are chickens who live on average 1⁄10 of a year (5-6 weeks), we get about $5/year vegan. This estimate is in line with ACE (https://animalcharityevaluators.org/research/donation-impact/) and Counting Animals (http://www.countinganimals.com/how-many-animals-does-a-vegetarian-save/): 400 lives/year vegan divided by 76000 lives/1000$= $5/year vegan.
The latter is the marginal impact, which is slightly better than the average in the US: $50.000.000/year donations to vegan and animal farm organisations divided by 5.000.000 vegans= $10/year vegan.
The offset price can increase in the future if it becomes more difficult to convert people to vegnism (if the low hanging fruit of meat eaters is already converted)
