Competition is an incredible driver of outcomes, e.g. moon landing. It's also better from a risk perspective since it decorrelates efforts and we only need 1 to succeed. It also allows evolution to operate, where the incompetent and broken and corrupt die off and the productive are given more resources, which tends to lead to overall improvement.
Sure, competition also creates waste, which is your main point here, but don't discount the upsides.
Competition has proven itself in the real world. Having only one monolithic vaccine maker (whether for-profit, non-profit, or government) would be a very bad thing. What would happen if it falls to corrupt leadership, as one of many examples of how this could go wrong? There is no mechanism to escape badness here, because we only have 1 of them.
