I would strongly urge people to err on the side of attendance. The value of the connections made at EAGs and EAGxs far exceeds the risks posed by most communicable diseases, especially if precautions are taken, such as wearing a mask.
If you take seriously the value of connections, many of them could very well exceed the cost to save a life. Would you say that your avoiding a cold is worth the death of someone in the developing world, for instance? I think your request fails to take seriously the value of making connections within the EA community.
I think there is a bit of a problem with the "favor" mindset and too much of the onus is put on the person seeking help.
People with power, money, connections, and influence, to the extent that they are EA, should use these capabilities for good, and often this can be through helping other EAs (or people, for that matter). Such big people are extremely busy, but this probably means that they should have systems in place to help them deploy their capabilities to effective uses. If this means hiring someone or referring someone else to screen requests, this might be necessary.
If Big EAs are not responsible with the use of their capabilities on behalf of other EAs, we will probably only reach a fraction of our capacity for doing good.
Potentially you could gather purchase commitments that are explicitly contingent on being able to be processed through GLO... Potentially you could offer inducements to the companies that accept GLO, such as an advertising deal with Google Maps or Waze that is like "Spend your GLO here at taco bell on a tasty cheesy gordita crunch." Idk
What can we do to signal to vendors that we would prefer/demand to be able to pay in GLO?
