You don't need to heat your home with fire, you're tying heating to fire just like you're tying production and infrastructure to Capitalism.
What I personally want, is what all leftists want at the core: worker ownership of the Means of Production, rather than individual. This has been expressed numerous ways, from Worker Co-operatives in developed nations, as a quick example.
When you attribute vaccines, supermarkets, computers, and so forth to Capitalism, you're stating that in order to have those, there must be individuals owning and controlling production dictatorially, rather than democratically.
Again: I'm advocating for Socialism. Worker Ownership of the Means of Production. This isn't throwing away infrastructure, just the concept of individual ownership. The economy would be massive and organized, just democratically rather than dictatorially.
