no it isn't
Those miners who missed the initial PoW distribution gets another chance and the community can support the coin by increasing buy pressure
First of all, this coin doesn't exist so miners get a chance to pump and dump it. The reason for PoS is to get rid of mining, which is a wasteful and useless activity.
And if this "buy pressure" is being generated by autoselling mined coins and then autobuying mint, it is just going to create a low ball buy wall and help drop the price.
What we want to do is to relieve selling pressure. You do this by not not selling your coins and holding them instead of selling them for a minor profit and waiting for the price to drop so you can buy back in and do it over and over again. That only increases volatility until the coin is useless as a currency. This is why alts die. They are too volatile to be used safely as currency.
We need to make this coin rarer and harder to get if we want the price to rise.
The future of MINT or any PoS coin is in becoming a utilitarian and useful currency.
And since mining them wont generate any more coins it will stay as rare as it is without mining.
