The original post is in relation to commercial solar PV, not residential, which is a power generator rather than power consumer.
Except via planning law, which is not in the direct control of grid operators (lobbying…), it is not within the gift of the grid operators to stop or agree to the co-location of batteries.
Given that both solar panels, and wind turbines, arr DC generators, the direct connection to batteries via DC-DC charge controllers (which is the most efficient way to charge batteries) does not have anything to do with grid operators, so their commercial interests are irrelevant to the implementation, if that is necessary to create a financially sustainable asset for the power plant owner.
In relation to residential solar PV…which I think you were commenting on, inverters can be set to zero export. If laws are created to specifically fuck over residential solar, the worst case will always be to decommission existing solar PV (say, it was taxed annually on a per panel basis, make it unlawful to self consume etc, but it is possible to set inverters to zero export so one should never have to pay a charge for exporting).
But so long as one can self consume and batteries are available (note even house batteries could be made unlawful, ie due to bullshit argument based on safety), there will always be a system that can reduce costs unless power costs 0 short of a truly broken system. ie grid operators charge power producers for both over production and at the same time charge users for using), but even then solar production cost is essentially 0: fill your own batteries and zero export once full, then discharge a portion at night if profitable.
Pumped hydro is without a doubt the most effective energy storage method but requires the right geology and geography, and is only part of a solution. Check the key statistics on this link to see just how nuts it can be when paired with reliable solar over production. https://british-hydro.org/pumped-storage-hydropower/
