It's easy to come up with a correct physical problem and
solve it with the wrong mathematics. As you did.

HdB has come up with a mathematical problem which he claims can end the
world:

HdB claimed that a discontinuity in a mathematical function of time
causes time to stop. And he claimed this followed from physics.

Thus, if HdB is right, the vase problem will cause the end of the
world.

Yes. If it came into _existence_, it would cause the end of the world.
Because an infinite mass would be no less than a Cosmic Disaster.

Since it _exists_ only as a gedankenexperiment, a sort of mental game,
such fears are irrelevant.

Other fears are more relevant. Such as the fear that infinities in
mathematics may easily lead to irrelevancies in physics (like e.g.
with Black Holes or String Theory)

As the almost universal consensus of astronomers now is that the center
of many, possibly most, galaxies is a huge black hole, and that many
larger stars too big to eventually collapse into neutron stars collapse
into black holes when they run out of fuel, it appears that HdB is the
unaware of what are irrelevancies in physics.

So that HdB is hardly in a position to dictate what should be considered
irrelevancies in areas outside of his supposed area of expertise.
