Most people don't have AI subscriptions. A lot of the most fervent detractor hate AI to the core and refuse to use it as much as possible.

Perhaps we should charge AI subscription "tax" to pay for more renewable energy.

Most consumers don't have any AI subscriptions. Lots of people's primary experience of AI is it being forced on them through integration into existing products and services, more "greed and hubris".

Is there any evidence that individualization of responsibility works better than government policy?

Personally I see no contradiction in using a product despite wanting policies that prevent it: it just implies that you understand the tragedy of the commons.

What if we never signed up?

Not sure if this is sarcastic, but there are effectively no consumers (as opposed to corporations) with AI subscriptions; the number of paid ChatGPT users is a rounding error. In the long run we should not expect the number of paid consumers for LLMs to be significantly greater than the number of paid consumers for search engines.
