No, the free market keeps prices low and competition high. Regulation only fucks things up.
First, it seems many "skaters" fail to see the indirect benefit in supporting the local shop. (Obviously not all local shops are worth supporting, but it seems most cities have one legit shop.) Not that my local shop always gets it right, but they've done amazing things to make the scene better. Reducing a shop to simply a place where goods are purchased misses a big part of the picture. The buying and selling of goods of almost incidental to the shop's real impact on the local scene.
On top of being a place to buy goods, shops act as a space to hang out (make friends, discussion of ideas, etc.), it is a place of "education" for younger skaters (the local shop is a way better place to learn about skateboarding than Aaron Kyro's latest "Will Xenu's spaceship skate?" video), the shop is a promotional platform for local skaters (shop TM's often act as agents for local flow skaters), the shop is an easy resource for the local governments to reach out to for assistance/advice, and so on. The shop's value is only partial found in its ability to sell product.
Second, the stupidity in the quoted statement is best seen in the fact that it has no relation to the past 40 years. (Not to mention Adam Smith our free market hero was fighting against mercantilism, which every libertarian seems to forget as the catch phrases are more fun than the actual theory).
In the post-Reagan "de-regulation" era we've only seen wealth continue to concentrate. This is within individuals and within most sectors of the economy. Hell, from 1996 to 2012 we saw most areas of the economy become more concentrated not more competitive.
Third, the quoted "logic" believes that the magic fairy's "invisible hand" will create and maintain competition forgets that money is a form of power that can allow a powerful individual or institution to manipulate and bastardize the market. If I am Microsoft or Home Depot or some other huge company am I really going to just watch the market change because " free choice"? No, I'm going to buy out my competition, I'm going to pay them not to produce, I'm going to hire market researchers to manipulate the public, and so on. I'm going to do everything I can to cling on to power.
A local shop is so much more than just a place to buy a board. Brands play a role as well, but it is kind of like the local gov vs the federal gov. It is sometimes easier to see the fed gov because it is so big and powerful, but the local gov is the one that has the biggest affect on our day to day lives. It is easy to see how Sorry impacted the skate scene as a whole, but difficult to see how important all the little things the local shop did to make and maintain our local scenes.
