Ah, so hope you're in a part of space with relevant in-zone coverage, otherwise you're shit out of luck.
That's pretty much how things work in a monetary system (which the Ferengi use and its rather consistent with their behaviour)... so, no surprise there.
A lot of people in real life end up out of luck when a paywall comes up and they are in the wrong region.
For example, Netflix doesn't show certain content in UK, but it does in USA... and vice verse, but everyone has to pay the local rate (which can be cheaper or more expensive depending on the region)... the situation is similar for other countries.
In some countries, you cannot access various web sites without a VPN (a piece of software that can similarly be inaccessible).
And of course, there's lack of internet coverage, or even if there is coverage, you're not guaranteed its going to work, etc.
Protostar cores just run, as does anything that draws energy from subspace.
Actually, the protostar core did not draw energy from subspace. Its been inferred that the protocore is an actual protostar.
Protostar Gravimetric containment... meaning the thing probably DOES emanate massive amounts of gravimetric energy, but SF hadn't figured out how to use the protocore to power its own containment or other systems (most likely because their power transfer conduits don't come close to being able to handle that much energy constantly (because they would be rated to handle something like two warp cores, or about 25.4 exawatts - but not anywhere close to say 1000 or 2000 exawatts which could be consistent with a 'baby star' power output) - hence the third nacelle - they can handle transmitting just enough energy for generating TW speeds in a relatively short burst, but not much else - hence why they still use Dilithium and M/AM to power the containment of the protocore itself and most other things onboard seeing how its a power mechanism SF is most accustomed to.
I suspect that there might be tremendeous power loss/inefficiency associated with the proto core because SF's power transfer conduits just can't handle a baby star level of energy.
SF needs to up its game in power transfew technology and/or control the proto core so it generates much less energy during 'normal' operations and more for proto Warp - but I suspect they would have needed more R&D for that - which would make sense in this context, but as a highly advanced alliance of numeros civilisations, it shouldn't be impossible to overcome in a few decades to half a century at most - but I guess the writers don't want that).
