America's 200+ year old democracy still has around 56% turnout for national and 27% turnout for local elections (quick Google 2020). This does not even address how poorly the current system still fails the 56% of people that manage to vote. It is not perfect.
If any alternative or improvement proposed to that system is held to a standard of 'must be perfect', I think they will fall short no matter how good the intention may be or how good it improves on the current way.
Buying a phone for someone so that your law gets one more vote will be very natural, so all the poor people will get new phones very soon. And that will not be a bad thing, because politician will not be able to buy votes then pass a law to take the same money back from people. In effect this will morph into a sort of UBI, where some people pay others to keep society running with laws that they think are beneficial for everyone. And people who think they know better will be able to gather in separate cities and try out the laws they think will be better.
I was proposing modifying how we interact with elected officials, not modifying how we elect them.
I realize there are bad actors actively working to suppress voters rights in many places in many ways. and I dont want to even be accidently hitched to that bandwagon.
