Yes, steam pipes embedded in walls have a lot of surface area and can put a lot of heat into the space, but it's at an uncontrolled rate. Using electric baseboard to heat the place is insanely expensive at NYC's electricity pricing to operate in comparison to a central gas boiler, even at the atrocious efficiency of some of those systems. The landlord saves a lot of money by only partially heating your space, but you make up the difference with the most expensive heat possible.
And unless the landlord will stipulate in writing that the pipes will always be hot when it's below 60F outside, the baseboard could be covering 100% of the heating load.
If the landlord were installing a ductless air source mini-split heat pump instead of baseboard it might be more reasonable for the tenant, since the efficiency of mini-splits is high in both heating and cooling mode (it's 2x as efficient as a window air conditioner, and 10x quieter), but that's a lot more expensive to install than electric baseboard.
