The point is that your proposal incentivises people to break the rules and cross unsafely; which is the opposite of what the proposal intends.
The incentive to break the rules and cross unsafely already exists. One part of my proposal (space crossings further apart) strengthens that incentive. Another part of my proposal (stop signs or traffic lights at each crossing) makes it safer to cross in accordance with the rules.
The reason for the former part is to preserve the usefulness of the roadway for drivers (which would otherwise be reduced by the increase in its safety), while the reason for the latter part is to increase the safety of the roadway for pedestrians.
On net, the roadway becomes safer but less useful for pedestrians, while remaining as useful as previously for drivers. (There is also a matter of safety for drivers, but not a significant one.)
The appropriate question here is what is more unsafe?
It is clear that cars not being forced to stop before zebra crossings is more unsafe.
If crossing in random places is dangerous and sanctioned crossings are less frequent, that does not mean that the road is less safe, only that it is less useful. Safety is to be evaluated on the basis of two things: (a) how safe it is to behave in the approved way, and (b) how easy it is to behave in the approved way and avoid behaving in the un-approved way, should one have a general intention to do so. Mere incentives to behave in the un-approved way are not properly understood to be components of safety, only of usefulness.
It is clear that cars not being forced to stop before zebra crossings is more unsafe.
Then let’s just get rid of zebra crossings all together. But I highly suspect that this would not be a good solution (eg. in Europe I have never seen a stop sign for a zebra crossing).
It’s an hyperbole, of course —to keep the usefulness of the road, if it is less dangerous that people just cross in random places than that cars stop before zebra crossings, let’s get rid of the crossings.

I don’t see how this follows…?

That would reduce the usefulness of the road for pedestrians to zero, which for most roads is too low.
In any case, your antecedent clause there is a mischaracterization of the discussion so far.
On the contrary, they could cross anywhere without needing to walk to the zebra crossing! That would increase the road’s usefulness for them.
But pedestrians can do that already, so your proposed change would not change this; thus there could be no increase.
Now it is illegal in some places and not recommended in others → social & cívic pressure against. Plus the increase in usefulness for the cars.
