Current architectures aren't ready to operate enough gates fast/accurate[1] enough to attempt sustained (i.e. longer than milliseconds) protection of quantum data. So making more qubits would not be very useful until we can make them talk to each other. [1]: Qubits are always decohering, so fast and accurate are closely linked.
