Q:

How can dhcpcd ignore static IP settings in /etc/dhcpcd.conf?

Yesterday I had to switch my home network back from DHCP to static IPs, but my Raspberry Pi 3B (with the current Raspbian) keeps on using an invalid IP address, namely:
eth0      Link encap:Ethernet  HWaddr b8:27:eb:4c:cb:8c  
          inet addr:169.254.168.86  Bcast:169.254.255.255  Mask:255.255.0.0
          inet6 addr: fe80::243a:4333:fc91:c87/64 Scope:Link

The address isn't even valid for my network, as its address is now this one: 169.254.164.0/24
After reading a couple of answers here at SE, I edited my /etc/dhcpcd.conf as follows:
# A sample configuration for dhcpcd.
# See dhcpcd.conf(5) for details.

# Allow users of this group to interact with dhcpcd via the control socket.
#controlgroup wheel

# Inform the DHCP server of our hostname for DDNS.
hostname

# Use the hardware address of the interface for the Client ID.
clientid
# or
# Use the same DUID + IAID as set in DHCPv6 for DHCPv4 ClientID as per  RFC4361.
#duid

# Persist interface configuration when dhcpcd exits.
persistent

# Rapid commit support.
# Safe to enable by default because it requires the equivalent option set
# on the server to actually work.
option rapid_commit

# A ServerID is required by RFC2131.
require dhcp_server_identifier

# Generate Stable Private IPv6 Addresses instead of hardware based ones
slaac private

# A hook script is provided to lookup the hostname if not set by the DHCP
# server, but it should not be run by default.
nohook lookup-hostname

# Configures eth0 for a static IP address and routing.
# Added 2017/12/25 by JR.
interface eth0
static ip_address = 169.254.164.3/24
static routers = 169.254.164.1
static domain_name_servers = 212.6.64.14

The DHCP client restarts nicely:

Dec 24 22:28:52 autoradio dhcpcd[1402]: eth0: no IPv6 Routers available

But: The client neither sets the IP address, nor standard route, so that I've gotta do this manually. Why? Does anybody know what's wrong here? Any help would be greatly appreciated.
UPDATE: The server is now complaining about a "martial" IP of my Raspi:
[15741.931325] IPv4: martian source 169.254.164.1 from 169.254.168.86, on dev eth2

UPDATE #2: Upon another user's request, here's the current dhcpcd.conf:
pi@autoradio:~ $ cat /etc/dhcpcd.conf
hostname

persistent

option rapid_commit

option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
option ntp_servers

require dhcp_server_identifier

slaac private

nohook lookup-hostname

# Configures eth0 for a static IP address and routing.

interface eth0
#static ip_address = 169.254.164.3/24
#static routers = 169.254.164.1
#static domain_name_servers = 212.6.64.14

A:

It is FUTILE trying to set a Link-local address
These are NOT routable and are NOT static.
If you absolutely MUST set a static address How to set up Static IP Address
explains how to do it.
