On the surface, this appears to be correct.

But let's ask ourselves _why_ those upstreams had bad routes. It's
because _they_ did not filter at the edge. If bad routes leak, but are
filtered before reaching the core, then they never make it to you.

IOW, your concern is a non-issue if the large providers apply similar
filtering at the edge. You wouldn't be cutting yourself off because the
provider in question would have filtered it long ago.

Do it at the edge, and the Internet does not become any more brittle.

As for making money... if the general agreement is that "BGP death
penalty" is correct, let the violators and bad BGP speakers face the
consequences of spewing garbage.
