It seems that the majority of SNOs that took this poll would prefer to wait for the threshold to be reached than to even use the zkSync / L2 solution.
There is no one solution to make everyone happy. Since Storj/Tardigrade is a business trying to make money, I am sure they have thought this through carefully before deciding on the L2 solution vs any of the other possible options.
Granted, I have been running nodes for a long time so I already have my own trust in Storj to pay me. That trust doesn’t come right away for new SNOs. But if Storj goes ahead and pays out all of these payments without mitigating the high costs of transactions, the entire venture could fail and then no one gets paid. I trust that they are doing their best to make this 
sandwich as palatable as possible since everyone here, including Storj, has to take a bite.
