To be any kind of leftist at all, you have to believe in equality in society, in providing for all, and opposing hierarchy. There are many interpretations of how to get to such a place, though socialism encompasses the biggest ones.

You can enjoy the things you have access to in the current system, but enjoying the system itself, which forces us to enrich billionaires, destroys the planet, pushes us into poverty, and wastes our time and potential working on what the market wants instead of what we want, is fundamentally anti-leftist.
