It must be nice to live in the Netherlands. > slow, expensive payment system using its own wildly fluctuating currency that consumes the energy of a small country You don't have to use Bitcoin, you can e.g. use a stablecoin on an Ethereum roll-up. It's not slow; transactions finalize within 1 minute (and soon, less). It's not expensive; it costs less than 10 cents (and soon, less). It doesn't fluctuate wildly, because it value is stabilized using one of several mechanisms. It doesn't consume the energy of a small country, because it does not use proof of work.
