ATHENS — Greek voters’ decisive rejection of Europe’s plan to bail out their country cast them closer than ever to doomsday scenarios: A collapse of the banks. An exit from the euro zone. A return to the drachma. But it is a price that 42-year-old Georgia Imsiritou said she is ready to pay. “That’s the only logical thing to do,” said Imsiritou, who was among the 61 percent of Greeks who voted Sunday against accepting the austerity measures that European officials have demanded in return for releasing more aid to the debt-ridden country.
