This is basically very similar to the ATOM staker CC tax being discussed in another thread in the forum. The suggestion here is to implement this tax as a gradual increase in the minimum commission, this is another solution yes and as you say ATOM stakers will be thinking a lot more about which CCs to approve.
I think it is totally the right place to discuss since it combines several solutions for different issues into one comprehensive solution actually. What do you think about this @Damien? It is an idea to easily implement the ATOM staker CC tax
Yes so if we don’t ask CCs to buy ATOM and stake it, there should also be a CC tax depending on the revenues on each. We cannot put infra cost tax for validators, now an ATOM stakers CC tax and the CCs themselves have no taxes, provide no revenues and have all the benefits. An idea to implement this tax as @pupmos suggested before is to raise the % of revenues from CCs going to the Cosmos Hub to at least cover the infra costs, if even increasing this % still negligable revenue then they should pay a tax variable depending on the revenues each CC is providing to the Cosmos Hub
