The people arguing against you are not going to see it your way.
There is a ideology of some people that think that taxes are a magical way of funding anything they feel is a common good. Most of the time these are well intended thoughts of public good. However they NEVER take into the account the unintended consequences of their ideas. It stops with tax more = more public good.
There are just as many people who seem to think that all taxes are inherently harmful for any possible use case and nothing will convince them otherwise. I would honestly expect fintech to have more of this group than the one you describe.
