@WI_Red's point about the sloth comment being outrageous: why would democratic participation have to involve as much work as possible? Do you want to encourage or discourage participation?
It's simply a fact that the indirect democratic systems that contemporary democratic countries employ (i.e, 'the people' don't decide on matters; they decide who gets to decide) generally don't do a great job at inciting people to care and vote. It's very hard to address that aspect: it requires changing electoral system so every vote counts (e.g., in first-past-the-post/winner-takes-all systems, voting left in an extremely right-leaning county is pretty pointless), and even then, many people will continue to feel disconnected, and especially those voting for parties that are never likely to make it into a majority government (single-party or coalition).
So to me, the sensible thing to do is to make voting as easy as possible, to help people participate in their democracies. Don't make it work; use whatever is available to make it easy! Allow people to vote at the time and day that works best for them, reduce ID requirements (they're hard on Indigenous people living on reserve in Canada, for example), and allow them to vote by mail an internet (once systems are ready for the latter; they are probably nearly there in countries like Finland and the Netherlands).
Worries about fraud are nonsense: there is no evidence anywhere for fraud happening at any significant scale.
