Liberal democracies are relatively new, but the process of deciding norms that satisfy different groups with conflicting interests is as old as the human history.
In Italy, for example, it's already like that: legislative proposals that are not approved by the parliament lapse at the end of the legislative term.
Laws are not simply voted by the parliament, presenting them it's a process per se, with its specific rules.
Throughout history many tricks have also been developed to work around the limitations of the system, for example presenting the same law with slightly different wordings or use amendment bombing to block some proposal ad libitum (in Italy this happens a lot, there have been examples of software programs written specifically to do that: emit an infinite number of amendments so that they would never run out of them)
Of course if some group is really determined or bears enough power it can push its own agenda while smaller less powerful ones can have a very hard time to get attention, even if their proposals are good. It's not ideal, but democracy it's a process to find tradeoffs, usually not the best one, but the lower common denominator one.
