The rumored problem with hot gas thrusters on Starship is the relatively low pressure of the propellant tanks. Electric pumps solve that, but add complexity. But what about pulsed thrusters?

I'm imagining something like this: Supply => main valve => regulator => check valve => accumulator => Tesla valve => injector

Potential issues would be vibrations (obviously) and controlling the mixture ratio. If the thrusters could be made small enough, vibrations might be minimized by clustering, with igniters timed so there's a continuous combustion.

Mixture ratio could be addressed by placing the regulator *after* the accumulator, but my gut says they'd get trashed by the pressure spikes.
