It would look really bad if the government of Chile was seen to be funding vacations. Unfortunately, that happens anyway. There are a bunch of people participating in the program that have done fuck all for the last six months and have little more to show for themselves than a Twitter account and some nice photos of the parties they've been to.
In all seriousness, this is why they shouldn't be investing in startups. Early stage investing is all about "throwing away" a bunch of money and (hopefully) making even more back when a subset of your portfolio wins big. If you're micromanaging each dollar/transaction, then you're really, really doing it wrong.
Saying investing in startups is all about "throwing away" a bunch of money isn't at all accurate.
The government of Chile isn't looking for a cash return on their investment, they're interested in the long term effects of having globally oriented entrepreneurs in the country interacting with future local entrepreneurs.
