As a rhetorical exercise, I just asked myself those questions (with
other words) in the very post you are replying to.
Please, read again.
If miners have a cost in including transactions (which they have) but
there's no gain, why are miners including free transactions?
Is it because they are stupid or because they don't care enough about
fees (and thus blindly use whatever default policy that comes with
Bitcoin Core)?

You are completely right, this is what matters in the end. To correct
myself, what I'm worried about is how low the fees/profits ratio is,
fees/total_reward is just an easier-to-calculate approximation when
you don't know costs =3D total_reward - profits.

Don't forget a rise in fees paid as another potential factor. That was
my whole point: higher fees may help reducing problems related to a
low fees/profits ratio.
And that's why I don't think a rise in fees is necessarily a bad thing.
Let's not forget that we're just talking about market fees for
non-urgent transfers rising above zero!
There may be a fee market for fast confirmations already, but there's
certainly none for non-urgent transfers.
In my opinion, rising from zero to anything, it's a great step
forwards. I can perfectly understand that maintaining that anything
low is good for adoption, but insisting in maintaining it at zero
doesn't seem very reasonable to me, given that we know for a fact that
is not sustainable in the long term.
We don't want business plans to fail because they're relaying on free
transactions. We don't want new users to be lied about the real
properties of the system.
And I'm sure that any ridiculously low value will be so marginally
worse for adaption when compared to a plain zero, that I'm not worried
about it at all.
Users starting to pay SOMETHING for a service they're enjoying and
that actually has quite big operational costs (energy-demanding proof
of work, currently subsidized by the finite initial seigniorage) it's,
by no means, the end of Bitcoin.
To me is really more of a start, a tiny first step towards a viable
system that doesn't depend on subsidies (with expiration date).
