Can anyone think of any good reason that a non-pro would wantg a power
sensor on their bike? If you ride enough to even think that you need one,
you can easily tell when you're in your Zone 2. And going all out to
detect you max power doesn't do you any good does it?

It’s seems to be a better way of training to power than by heart rate, more reliable way to measure one’s efforts.
If one is going to train power would seem the most useful metric.

A power meter is simply for consistent. You as a rider can think of your heart as a power meter and it can give good stats but no consistent.
Normally when you produce more power your heart rate goes up but other
things come into play.
The level of hydration and your physical state vastly change what your
heart rate may do on any given day. I don't have an outside power meter
but my indoor trainer does. It is very consistent. My heart rate can
vary over a 30 mile inside ride from 110-140 bpm on average but the over power will be different with some correlations but not always.
I find if I am well rest my heart rate will be considerably higher after taking of 2 days. Then after this I still sometime produce about the
same power stats but HR is much lower.
Power Meter is gold standard.

Training with a power meter takes a lot of guesswork out of the task.
IOW, power is power, you really can't fool it. Training by HR is a
reasonable alternative, but HR is subject to a great number of factors
such as ambient temperature, physical state (sickness, tiredness,
attitude). Also HR has an annoying habit known as cardiac Drift - where
a steady state power output will inevitably lead to a rising heart rate
and a resulting increase of Rate of Perceived Exertion (RPE). This is
what tommy is referring to with 'you know you're in zone 2'. There is a
bit of truth to that, but your perceived exertion is highly subjective.
Power meter accuracy doesn't deviate or drift (unless it's defective).
If you put out 250 watts over an hour, it'll tell you. It isn't left up
'wow I feel like I worked out really hard today', Watts don't lie.
Besides that, zones are generally defined by power. If you don't have ramp/threshold data, you don't know what 'zone 2' actually is. Again,
you can do it with heart rate, but as mentioned HR data is highly
subject to other forces.
One doesn't need to be a pro to train with a power meter. A lot of us do
it with good results.

I have to add that POWER does not give you some idea of effort. From day
to day and ride to ride the ability of your body to generate power
changes and if you're using power as a measurement you can hurt yourself
just as much as without a power meter. Youy train to perceived effort and
on bad days that is less than what a power meter shows.

I don’t think you’ve grasped how people are using power meters!
Aka people absolutely will note effort both perception and watts, or rather use it in a more nuanced way than your suggesting, which is what folks I
know who have them do.
