If there were no microservices, a lot of companies would run their monoliths on a few VMs, with a small fraction of the cost ;)
I think you inadvertently pointed out one of the advantages of microservices: the ability to bootstrap ideas without having to be hindered by artificial barriers to entry. If you have an idea and want to show it off, you just implement it and make it available to the public. Call it "aspirational goals", but I don't see any advantage in barring people from providing value without having to wrangle bureaucracies, red tape, and office politics.
If you keep the infrastructure simple, it’s also much easier to switch cloud provider and to set up testing systems.
