I like this idea! One problem though, the government is quite likely to pick a blockchain like ETH or BTC with transaction fees. Or even worse, try to build their own chain 🤯 I don't like pay-to-pay stuff - be it blockchains or entrance fees to a pub - and I have very little trust that building a new chain instead of using something that already exists (Hive, WAX, Nano, Banano... are all fast and fee-less!) would turn out cheaper, better, more transparent, or easier to use.

Also, a chain with transaction fees would be a terrible choice if people are expected to use it for voting. "Hmm, shall I give the kids dinner today, or spend the money on voting against defunding their school?" Not very many will say "Sorry kids, education is more important, and maybe you'll get something nice for school lunch tomorrow, unless they've cancelled lunch." so only the rich would be able to vote freely on every issue.
