There's a difference between storing the content itself, and storing just a
hash to content (which however is not spendable payment). I undertand why
content itself doesn't belong. But it goes too far to say that only
payments should be allowed.

If the fees are not enough, fix the fee structure, don't stop incredibly
innovative and promising uses of the distributed timestamping database.
That is definitely throwing the baby out with the bathwater. If the issue
is size, then address that, rather than the content itself.

Have I misunderstood this discussion or are some proposing than nothing
except payments be allowed?

Discriminating based on transaction content violates neutrality of the
protocol and in my mind removes a very very large possibility of future
innovation. If bitcoin is a *platform* and not just a payment system, then
it needs to be neutral to content, like TCP/IP so that other protocols can
be layered. Solve the size problem itself, without picking and chosing
which uses of bitcoin are good and which are "bad" or "spam". I think it
risks killing a tremendous amount of innovation just as it is starting.

Again, I think it is extreme and extremely restrictive to say that ONLY
payments are allowed.

Can you explain this part or refer me to some docs? What do you mean by
"coinbase", I assume not the company.

Thanks for the reply and explanation!
